Timeline of the Syrian Civil War
This is a broad timeline of the course of major events of the Syrian Civil War. It only includes major territorial changes and attacks and does not include every event.
The uprising against Syrian president Bashar al-Assad gradually turned into a full-scale civil war, with two significant milestones being the initial March 2011 Arab Spring protests and the 15 July 2012 declaration by the International Committee of the Red Cross that the fighting had gradually become so widespread that the situation should be regarded as a civil war.
It has been 7 years, 7 months and 1 day since the Syrian Day of Rage protests were staged on 15 March 2011.
It has been 6 years, 3 months and 1 day since the Red Cross declared the situation to be a civil war.

Protests, civil uprising, and defections (March–July 2011)
The protests began on 15 March 2011, when protesters marched in the capital of Damascus, demanding democratic reforms and the release of political prisoners. Security forces retaliated by opening fire on the protesters, and according to witnesses who spoke to the BBC, the government forces detained six of them. The protest was triggered by the arrest of a boy and his friends by the government for writing in graffiti, "The people want the fall of the regime", in the city of Daraa. Writer and analyst Louai al-Hussein, referencing the Arab Spring ongoing at that time, wrote that, "Syria is now on the map of countries in the region with an uprising". On 20 March, the protesters burned down a Ba'ath Party headquarters and "other buildings". The ensuing clashes claimed the lives of seven police officers and 15 protesters. Ten days later in a speech, President Bashar al-Assad blamed "foreign conspirators" pushing Israeli propaganda for the protests.
Until 7 April, the protesters predominantly demanded democratic reforms, release of political prisoners, an increase in freedoms, abolition of the emergency law and an end to corruption. After 8 April, the emphasis in demonstration slogans shifted slowly towards a call to overthrow the Assad government. Protests spread; on Friday 8 April, they occurred simultaneously in ten cities. By Friday 22 April, protests were taking place in twenty cities. On 25 April, the Syrian Army initiated a series of large-scale deadly military attacks on towns with tanks, infantry carriers, and artillery, leading to hundreds of civilian deaths. By the end of May 2011, 1,000 civilians and 150 soldiers and policemen had been killed and thousands detained; among the arrested were many students, liberal activists and human rights advocates.
Unverified reports claim that a portion of the security forces in Jisr al-Shugur defected after secret police and intelligence officers executed soldiers who had refused to fire on civilians. Later, more protesters in Syria took up arms, and more soldiers defected to protect protesters.
Initial armed insurgency (July 2011–April 2012)
Early insurgency phase of the Syrian Civil War lasted from late July 2011 to April 2012, and was associated with the rise of armed oppositional militias across Syria and the beginning of armed rebellion against the authorities of the Syrian Arab Republic. Though armed insurrection incidents began as early as June 2011 when rebels killed 120-140 Syrian security personnel, the beginning of organized insurgency is typically marked by the formation of the Free Syrian Army (FSA) on 29 July 2011, when a group of defected officers declared the establishment of the first organized oppositional military force. Composed of defected Syrian Armed Forces personnel, the rebel army aimed to remove Bashar al-Assad and his government from power.
This period of the war saw the initial civil uprising take on many of the characteristics of a civil war, according to several outside observers, including the United Nations Commission on Human Rights, as armed elements became better organized and began carrying out successful attacks in retaliation for the crackdown by the Syrian government on demonstrators and defectors.
The Arab League monitoring mission, initiated in December 2011, ended in failure by February 2012, as Syrian Ba'athist troops and oppositional militants continued to do battle across the country and the Syrian Ba'athist government prevented foreign observers from touring active battlefields, including besieged oppositional strongholds.
In early 2012, Kofi Annan acted as the UN–Arab League Joint Special Representative for Syria. His peace plan provided for a ceasefire, but even as the negotiations for it were being conducted, the rebels and the Syrian army continued fighting even after the peace plan.:11 The United Nations-backed ceasefire was brokered by special envoy Kofi Annan and declared in mid-April 2012.
Ceasefire attempt (April–May 2012)
Kofi Annan was acting as UN–Arab League Joint Special Representative for Syria. His peace plan provided for a ceasefire, but even as the negotiations for it were being conducted, Syrian armed forces attacked a number of towns and villages, and summarily executed scores of people.:11 Incommunicado detention, including of children, also continued. In April, Assad began employing attack helicopters against rebel forces.
On 12 April, both sides, the Syrian Government and rebels of the FSA entered a UN-mediated ceasefire period. It was a failure, with infractions of the ceasefire by both sides resulting in several dozen casualties. Acknowledging its failure, Annan called for Iran to be "part of the solution", though the country has been excluded from the Friends of Syria initiative. The peace plan practically collapsed by early June and the UN mission was withdrawn from Syria. Annan officially resigned in frustration on 2 August 2012.
Renewed fighting (June–October 2012)
Following the Houla massacre of 25 May 2012, in which 108 people were summarily executed and the consequent FSA ultimatum to the Syrian government, the ceasefire practically collapsed, as the FSA began nationwide offensives against government troops. On 1 June, President Assad vowed to crush the anti-government uprising.
On 5 June, fighting broke out in Haffa and nearby villages in the coastal governorate of Latakia Governorate. Government forces were backed by helicopter gunships in the heaviest clashes in the governorate since the revolt began. Syrian forces seized the territory following days of fighting and shelling. On 6 June, 78 civilians were killed in the Al-Qubeir massacre. According to activist sources, government forces started by shelling the village before the Shabiha militia moved in. The UN observers headed to Al-Qubeir in the hope of investigating the alleged massacre, but they were met with a roadblock and small arms fire and were forced to retreat.
On 12 June 2012, the UN for the first time officially proclaimed Syria to be in a state of civil war. The conflict began moving into the two largest cities, Damascus and Aleppo. In both cities, peaceful protests – including a general strike by Damascus shopkeepers and a small strike in Aleppo were interpreted as indicating that the historical alliance between the government and the business establishment in the large cities had become weak.
On 22 June, a Turkish F-4 fighter jet was shot down by Syrian government forces, killing both pilots. Syria and Turkey disputed whether the jet had been flying in Syrian or international airspace when it was shot down. Despite Turkish Prime Minister Recep Tayyip Erdoğan's vows to retaliate harshly against Assad's government, no such intervention materialised. Bashar al-Assad publicly apologised for the incident. By 10 July, rebel forces had captured most of the city of Al-Qusayr, in Homs Governorate, after weeks of fighting. By mid-July, rebels had captured the town of Saraqeb, in Idlib Governorate.
By mid-July 2012, with fighting spread across the country and 16,000 people killed, the International Committee of the Red Cross declared the conflict a civil war. Fighting in Damascus intensified, with a major rebel push to take the city. On 18 July, Syrian Defense Minister Dawoud Rajiha, former defense minister Hasan Turkmani, and the president's brother-in-law General Assef Shawkat were killed by a suicide bomb attack in Damascus. The Syrian intelligence chief Hisham Ikhtiyar, who was injured in the same explosion, later succumbed to his wounds. Both the FSA and Liwa al-Islam claimed responsibility for the assassination.
In mid-July, rebel forces attacked Damascus and were repelled in two weeks, although fighting still continued in the outskirts. After this, the focus shifted to the battle for control of Aleppo. On 25 July, multiple sources reported that the Assad government was using fighter jets to attack rebel positions in Aleppo and Damascus, and on 1 August, UN observers in Syria witnessed government fighter jets firing on rebels in Aleppo. In early August, the Syrian Army recaptured Salaheddin district, an important rebel stronghold in Aleppo. In August, the government began using fixed-wing warplanes against the rebels.
On 19 July, Iraqi officials reported that the FSA had gained control of all four border checkpoints between Syria and Iraq, increasing concerns for the safety of Iraqis trying to escape the violence in Syria. On 19 September, rebel forces seized a border crossing between Syria and Turkey in Raqqa Governorate. It was speculated that this crossing could provide opposition forces with strategic and logistical advantages due to Turkish support of the rebels, whose headquarters subsequently relocated from southern Turkey into northern Syria.
In October, rebel forces seized control of Maarat al-Numan, a town in Idlib Governorate on the highway linking Damascus with Aleppo and captured Douma, marking increased influence in Rif Dimashq. Lakhdar Brahimi arranged for a ceasefire during Eid al-Adha in late October, but it quickly collapsed.
On 6 September 2012 Kurdish activists reported that 21 civilians were killed in the Kurdish neighborhood of Sheikh Maqsud in Aleppo, when the Syrian Army shelled the local mosque and its surroundings. Despite the district being neutral during the Battle of Aleppo and free of government and FSA clashes, local residents believed that the district was shelled as retaliation for sheltering anti-government civilians from other parts of the city. In a statement released shortly after the deaths, the Kurdish People's Protection Units (YPG) vowed to retaliate. A few days later, Kurdish forces killed 3 soldiers in Afrin (Kurdish: Efrîn) and captured a number of other government soldiers in Ayn al-Arab (Kurdish: Kobanî) and Al-Malikiyah (Kurdish: Dêrika Hemko) from where they drove the remaining government security forces. It was also reported that the government had begun to arm Arab tribes around Qamishli in preparation for a possible confrontation with Kurdish forces, who still did not completely control the city.
At least 8 government soldiers were killed and 15 wounded by a car bomb in the al-Gharibi district of Qamishli on 30 September 2012. The explosion targeted the Political Security branch.
Rebel offensives (November 2012 – April 2013)
After Brahimi's ceasefire agreement ended on 30 October, the Syrian military expanded its aerial bombing campaign in Damascus. A bombing of the Damascus district of Jobar was the first instance of a fighter jet being used to bomb Damascus. The following day, Gen. Abdullah Mahmud al-Khalidi, a Syrian Air Force commander, was assassinated by opposition gunmen in the Damascus district of Rukn al-Din. In early November 2012, rebels made significant gains in northern Syria. The rebel capture of Saraqib in Idlib Governorate, which lies on the M5 highway, further isolated Aleppo. Due to insufficient anti-aircraft weapons, rebel units attempted to nullify the government's air power by destroying landed helicopters and aircraft on air bases. On 3 November, rebels launched an attack on the Taftanaz air base.
On 18 November, rebels took control of Base 46 in the Aleppo Governorate, one of the Syrian Army's largest bases in northern Syria, after weeks of intense fighting. Defected General Mohammed Ahmed al-Faj, who commanded the assault, stated that nearly 300 Syrian troops had been killed and 60 had been captured, with rebels seizing large amounts of heavy weapons, including tanks. On 22 November, rebels captured the Mayadin military base in the country's eastern Deir ez-Zor Governorate. Activists said this gave the rebels control of a large amount of territory east of the base, stretching to the Iraqi border. On 29 November, at approximately 10:26 UTC, the Syrian Internet and phone service was shut off for a two-day period. Syrian government sources denied responsibility and blamed the blackout on fiber optic lines near Damascus becoming exposed and damaged; Edward Snowden in August 2014 claimed that this Internet breakdown had been caused, though unintendedly, by hackers of the NSA during an operation to intercept Internet communication in Syria.
In mid-December 2012, American officials said that the Syrian military had fired Scud ballistic missiles at rebel fighters inside Syria. Reportedly, six Scud missiles were fired at the Sheikh Suleiman base north of Aleppo, which rebel forces had occupied. It is unclear whether the Scuds hit the intended target. The government denied this claim. Later that month, a further Scud attack took place near Marea, a town north of Aleppo near the Turkish border. The missile appeared to have missed its target. That same month, the British Daily Telegraph reported that the FSA had now penetrated into Latakia Governorate's coast through Turkey. In late December, rebel forces pushed further into Damascus, taking control of the adjoining Yarmouk and Palestine refugee camps, pushing out pro-government Popular Front for the Liberation of Palestine-General Command fighters with the help of other factions. Rebel forces launched an offensive in Hama Governorate, later claiming to have forced army regulars to evacuate several towns and bases, and stating that "three-quarters of western rural Hama is under our control." Rebels also captured the town of Harem near the Turkish border in Idlib Governorate, after weeks of heavy fighting.
On 11 January 2013, Islamist groups, including al-Nusra Front, took full control of the Taftanaz air base in the Idlib Governorate, after weeks of fighting. The air base was often used by the Syrian military to carry out helicopter raids and deliver supplies. The rebels claimed to have seized helicopters, tanks and multiple rocket launchers, before being forced to withdraw by a government counter-attack. The leader of the al-Nusra Front said the amount of weapons they took was a "game changer". On 11 February, Islamist rebels captured the town of Al-Thawrah in Raqqa Governorate and the nearby Tabqa Dam, Syria's largest dam and a key source of hydroelectricity. The next day, rebel forces took control of Jarrah air base, located 60 kilometres (37 mi) east of Aleppo. On 14 February, fighters from al-Nusra Front took control of Shadadeh, a town in Al-Hasakah Governorate near the Iraqi border.
On 20 February, a car bomb exploded in Damascus near the Ba'ath Syrian Regional Branch headquarters, killing at least 53 people and injuring more than 235. None of the groups claimed responsibility. On 21 February, the FSA in Quasar began shelling Hezbollah positions in Lebanon. Prior to this, Hezbollah had been shelling villages near Quasar from within Lebanon. A 48-hour ultimatum was issued by a FSA commander on 20 February, warning the militant group to stop the attacks.
On 2 March, intense clashes between rebels and the Syrian Army erupted in the city of Raqqa, with many reportedly killed on both sides. On the same day, Syrian troops regained several villages near Aleppo. By 3 March, rebels had overrun Raqqa's central prison, allowing them to free hundreds of prisoners, according to the SOHR. The SOHR also stated that rebel fighters were now in control of most of an Aleppo police academy in Khan al-Asal, and that over 200 rebels and government troops had been killed fighting for control of it.
By 6 March, the rebels had captured the city of Raqqa, effectively making it the first provincial capital to be lost by the Assad government. Residents of Raqqa toppled a bronze statue of his late father Hafez al-Assad in the centre of the city. The rebels also seized two top government officials. On 18 March, the Syrian Air Force attacked rebel positions in Lebanon for the first time. The attack occurred at the Wadi al-Khayl Valley area, near the town of Arsal. On 21 March, a suspected suicide bombing in the Iman Mosque in Mazraa district killed as many as 41 people, including the pro-Assad Sunni cleric, Sheikh Mohammed al-Buti. On 23 March, several rebel groups seized the 38th division air defense base in southern Daraa Governorate near a highway linking Damascus to Jordan. On the next day, rebels captured a 25 km strip of land near the Jordanian border, which included the towns of Muzrib, Abdin, and the al-Rai military checkpoint.
On 25 March, rebels launched one of their heaviest bombardments of Central Damascus since the revolt began. Mortars reached Umayyad Square, where the Ba'ath Party headquarters, Air Force Intelligence and state television are located. On 26 March, near the Syrian town of al-Qusayr, rebel commander Khaled al Hamad, who commands the Al Farooq al-Mustakilla Brigade and is also known by his nom de guerre Abu Sakkar, ate the heart and liver of a dead soldier and said "I swear to God, you soldiers of Bashar, you dogs, we will eat from your hearts and livers! O heroes of Bab Amr, you slaughter the Alawites and take out their hearts to eat them!" in an apparent attempt to increase sectarianism. Video of the event emerged two months later and resulted in considerable outrage, especially from Human Rights Watch which classified the incident as a war crime. According to the BBC, it was one of the most gruesome videos to emerge from the conflict to-date. On 29 March, rebels captured the town of Da'el after fierce fighting. The town is located in Daraa Governorate, along the highway connecting Damascus to Jordan. On 3 April, rebels captured a military base near the city of Daraa.
In mid-January 2013, as clashes re-erupted between rebels and Kurdish forces in Ras al-Ayn, YPG forces moved to expel government forces from oil-rich areas in Hassakeh Province. Clashes broke out from 14 to 19 January between the army and YPG fighters in the Kurdish village of Gir Zîro (Tall Adas), near al-Maabadah (Kurdish: Girkê Legê), where an army battalion of around 200 soldiers had been blockaded since 9 January. YPG forces claimed to have expelled government after the clashes. One soldier was reportedly killed and another eight injured, while seven were captured (later released) and 27 defected. Fighting at the oil field near Gir Zîro ended on 21 January, when government forces withdrew after receiving no assistance from Damascus. In Rumeilan, directly west of al-Maabadah, another 200 soldiers had been surrounded by YPG forces, and 10 soldiers were reported to have defected.
From 8 to 11 February, heavy clashes broke out between the YPG and government troops in the PYD/YPG-held district Ashrafiyah where, according to SOHR, at least 3 soldiers and 5 pro-government militiamen were killed. The fighting followed deadly shelling on 31 January on Ashrafiyah, in which 23 civilians were killed after FSA units moved into the Kurdish sector of Aleppo. According to its own reports, the YPG lost 7 of its members in the fighting, while also claiming that 48 soldiers were killed and 22 captured, and a further 70 injured.
In early March, YPG forces established full control of oil fields and installations in north-east Syria after government forces posted there surrendered. Also, YPG assaulted government forces and took control of the towns of Tall ʿAdas, which is adjacent to Rumeilan oil fields, and Al-Qahtaniya (Kurdish: Tirbespî).
Government offensives (April–June 2013)
On 17 April, government forces breached a six-month rebel blockade in Wadi al-Deif, near Idlib. Heavy fighting was reported around the town of Babuleen after government troops attempt to secure control of a main highway leading to Aleppo. The break in the siege also allowed government forces to resupply two major military bases in the region which had been relying on sporadic airdrops. On 18 April, the FSA took control of Al-Dab'a Air Base near the city of al-Qusayr. The base was being used primarily to garrison ground troops. Meanwhile, the Syrian Army re-captured the town of Abel. The SOHR said the loss of the town would hamper rebel movements between al-Qusayr and Homs city. The capture of the airport would have relieved the pressure on the rebels in the area, but their loss of Abel made the situation more complicated. The same day, rebels reportedly assassinated Ali Ballan, who was a government employee, in the Mazzeh district of Damascus. On 21 April, government forces captured the town of Jdaidet al-Fadl, near Damascus.
In April, government and Hezbollah forces launched an offensive to capture areas near al-Qusayr. On 21 April, pro-Assad forces captured the towns of Burhaniya, Saqraja and al-Radwaniya near the Lebanese border. By this point, eight villages had fallen to the government offensive in the area. On 24 April, after five weeks of fighting, government troops re-took control of the town of Otaiba, east of Damascus, which had been serving as the main arms supply route from Jordan. Meanwhile, in the north of the country, rebels took control of a position on the edge of the strategic Mennagh Military airbase, on the outskirts of Aleppo. This allowed them to enter the airbase after months of besieging it.
On 2 May, government forces captured the town of Qaysa in a push north from the city's airport. Troops also retook the Wadi al-Sayeh central district of Homs, driving a wedge between two rebel strongholds. SOHR reported a massacre of over 100 people by the Syrian Army in the coastal town of Al Bayda, Baniyas. However, this could not be independently verified due to movement restrictions on the ground. Yet the multiple video images that residents said they had recorded – particularly of small children, were so shocking that even some government supporters rejected Syrian television's official version of events, that the army had simply "crushed a number of terrorists."
Continued fighting (July–October 2013)
On 28 June, rebel forces captured a major military checkpoint in the city of Daraa. On 12 July FSA reported that one of its commanders, Kamal Hamami, had been killed by Islamists a day before. The rebels declared that the assassination by the Islamic State of Iraq and Levant, was tantamount to a declaration of war. On 17 July, FSA forces took control of most of the southern city of Nawa after seizing up to 40 army posts stationed in the city. On 18 July, Kurdish YPG forces secured control of the northern town of Ras al-Ain, after days of fighting with the al-Nusra Front. In the following three months, continued fighting between Kurdish and mainly jihadist rebel forces led to the capture of two dozen towns and villages in Hasakah Governorate by Kurdish fighters, while the Jihadists made limited gains in Aleppo and Raqqa governorates after they turned on the Kurdish rebel group Jabhat al-Akrad over its relationship with the YPG. In Aleppo Governorate, Islamists massacred the Kurds leading to a mass migration of civilians to the town of Afrin.
On 22 July, FSA fighters seized control of the western Aleppo suburb of Khan al-Asal. The town was the last government stronghold in the western portion of Aleppo Governorate. On 25 July, the Syrian Army secured the town of al-Sukhnah, after expelling the al-Nusra Front. On 27 July, after weeks of fighting and bombardment in Homs, the Syrian Army captured the historic Khalid ibn al-Walid Mosque, and two days later, captured the district of Khaldiyeh.
On 4 August, around 10 rebel brigades, launched a large-scale offensive on the government stronghold of Latakia Governorate. Initial attacks by 2,000 opposition members seized as many as 12 villages in the mountainous area. Between 4 and 5 August 20 rebels and 32 government soldiers and militiamen had been killed in the clashes. Hundreds of Alawite villagers fled to Latakia. By 5 August, rebel fighters advanced to 20 kilometers from Qardaha, the home town of the Assad family. However, in mid-August, the military counter-attacked and recaptured all of the territory previously lost to the rebels in the coastal region during the offensive. A Syrian security force source "told AFP the army still had to recapture the Salma region, a strategic area along the border with Turkey." According to a Human Rights Watch report 190 civilians were killed by rebel forces during the offensive, including at least 67 being executed. Another 200 civilians, primarily women and children, were taken hostage.
On 6 August, rebels captured Menagh Military Airbase after a 10-month siege. The strategic airbase is located on the road between Aleppo city and the Turkish border. On 21 August, a chemical attack took place in the Ghouta region of the Damascus countryside, leading to thousands of casualties and several hundred dead in the opposition-held stronghold. The attack was followed by a military offensive by government forces into the area, which had been hotbeds of the opposition. On 24 August, rebels captured the town of Ariha. However, government forces recaptured Ariha on 3 September. On 26 August, rebel forces took over the town of Khanasir in Aleppo Governorate which was the government's last supply route for the city of Aleppo. On 8 September, rebels led by the al-Nusra Front captured the Christian town of Maaloula, 43 km north of Damascus, The Syrian Army launched a counterattack a few days later, recapturing the town.
On 18 September, the Islamic State of Iraq and the Levant (ISIS) overran the FSA-held town of Azaz in the north. The fighting was the most severe since tensions rose between militant factions in Syria earlier in the year. Soon after ISIS captured Azaz, a ceasefire was announced between the rival rebel groups. However, in early October, more fighting erupted in the town. On 20 September, Alawite militias including the NDF killed 15 civilians in the Sunni village of Sheik Hadid in Hama Governorate. The massacre occurred in retaliation for a rebel capture of the village of Jalma, in Hama, which killed five soldiers, along with the seizure of a military checkpoint which killed 16 soldiers and 10 NDF militiamen. In mid-September, the military captured the towns of Deir Salman and Shebaa on the outskirts of Damascus. The Army also captured six villages in eastern Homs. Fighting broke out in those towns again in October.
On 28 September, rebels seized the Ramtha border post in Daraa Governorate on the Syria Jordan crossing after fighting which left 26 soldiers dead along with 7 foreign rebel fighters. On 3 October, AFP reported that Syria's army re-took the town of Khanasir, which is located on a supply route linking central Syria to the city of Aleppo. On 7 October, the Syrian Army managed to reopen the supply route between Aleppo and Khanasir.
On 9 October, rebels seized the Hajanar guard post on the Jordanian border after a month of fierce fighting. Rebels were now in control of a swath of territory along the border from outside of Daraa to the edge of Golan Heights. The same day, Hezbollah and Iraqi Shiite fighters, backed up by artillery, air-strikes and tanks, captured the town of Sheikh Omar, on the southern outskirts of Damascus. Two days later, they also captured the towns of al-Thiabiya and Husseiniya on the southern approaches to Damascus. The capture of the three towns strengthened the government hold on major supply lines and put more pressure on rebels under siege in the Eastern Ghouta area. On 14 October, SOHR reported that rebels captured the Resefa and Sinaa districts of Deir ez-Zor city, as well as Deir ez-Zor's military hospital.
Government offensives (October–December 2013)
The Syrian Army along with its allies, Hezbollah and the al-Abas brigade, launched an offensive on Damascus and Aleppo. On 16 October, AFP reported that Syrian troops recaptured the town of Bweida, south of Damascus. On 17 October, the Syrian government's head of Military Intelligence in Deir ez-Zor Governorate, Jameh Jameh, was assassinated by rebels in Deir ez-Zor city. SOHR reported that he had been shot by a rebel sniper during a battle with rebel brigades. On 24 October, the Syrian Army retook control of the town of Hatetat al-Turkman, located southeast of Damascus, along the Damascus International Airport road.
On 26 October, Kurdish rebel fighters seized control of the strategic Yarubiya border crossing between Syria and Iraq from al-Nusra in Al Hasakah Governorate. Elsewhere, in Daraa Governorate, rebel fighters captured the town of Tafas from government forces after weeks of clashes which left scores dead. On 1 November, the Syrian Army retook control of the key city of Al-Safira and the next day, the Syrian Army and its allies recaptured the village of Aziziyeh on the northern outskirts of Al-Safira. From early to mid-November, Syrian Army forces captured several towns south of Damascus, including Hejeira and Sbeineh. Government forces also recaptured the town of Tel Aran, southeast of Aleppo, and a military base near Aleppo's international airport.
On 10 November, the Syrian Army had taken full control of "Base 80", near Aleppo's airport. According to the SOHR, 63 rebels, and 32 soldiers were killed during the battle. One other report put the number of rebels killed between 60 and 80. Army units were backed-up by Hezbollah fighters and pro-government militias during the assault. The following day, government forces secured most of the area around the airport. On 13 November, government forces captured most of Hejeira. Rebels retreated from Hejeira to Al-Hajar al-Aswad. However, their defenses in besieged districts closer to the heart of Damascus were still reportedly solid. On 15 November, the Syrian Army retook control of the city of Tell Hassel near Aleppo. On 18 November, the Syrian troops stormed the town of Babbila. On 19 November, government forces took full control of Qara. The same day, the Syrian Army captured al-Duwayrinah. On 23 November, al-Nusra Front and other Islamist rebels captured the al-Omar oil field, Syria's largest oil field, in Deir al-Zor Governorate causing the government to rely almost entirely on imported oil. On 24 November, rebels captured the towns of Bahariya, Qasimiya, Abbadah, and Deir Salman in Damascus's countryside. On 28 November, the Syrian Army recaptured Deir Attiyeh.
On 2 December, rebels led by the Free Syrian Army recaptured the historic Christian town of Ma'loula. After the fighting, reports emerged that 12 nuns had been abducted by the rebels. However, the FSA disputes this and said that the nuns had been evacuated to the nearby rebel held town of Yabrud due to the Army shelling. In early December, the Islamic Front seized control of Bab al-Hawa border crossing with Turkey, which had been in hands of FSA. The groups also captured warehouses containing equipment delivered by the U.S. In response, the U.S. and Britain said they halted all non-lethal aid to the FSA, fearing that further supplies could fall in hands of al-Qaeda militants. On 9 December, the Army took full control of Nabek, with fighting continuing in its outskirts.
Fighting between ISIS and other rebel groups (January–March 2014)
Tension between moderate rebel forces and ISIS had been high since ISIS captured the border town of Azaz from FSA forces on 18 September 2013. Conflict was renewed over Azaz in early October and in late November ISIS captured the border town of Atme from an FSA brigade. On 3 January 2014, the Army of the Mujahideen, the Free Syrian Army and the Islamic Front launched an offensive against ISIS in Aleppo and Idlib governorates. A spokesman for the rebels said that rebels attacked ISIS in up to 80% of all ISIS held villages in Idlib and 65% of those in Aleppo.
By 6 January, opposition rebels managed to expel ISIS forces from the city of Raqqa, ISIS's largest stronghold and capital of the Raqqa Governorate. On 8 January, opposition rebels expelled most ISIS forces from the city of Aleppo, however ISIS reinforcements from the Deir ez-Zor Governorate managed to retake several neighborhoods of the city of Raqqa. By mid January ISIS retook the entire city of Raqqa, while rebels expelled ISIS fighters fully from Aleppo city and the villages west of it.
On 29 January, Turkish aircraft near the border fired on an ISIS convoy inside the Aleppo province of Syria, killing 11 ISIS fighters and 1 ISIS emir. In late January it was confirmed that rebels had assassinated ISIS's second in command, Haji Bakr, who was al-Qaeda's military council head and a former military officer in Saddam Hussein's army. By mid-February, the al-Nusra Front joined the battle in support of rebel forces, and expelled ISIS from the Deir Ezzor Governorate. By March, the ISIS forces fully retreated from the Idlib Governorate. On 4 March, ISIS retreated from the border town of Azaz and other nearby villages, choosing instead to consolidate around Raqqa in an anticipation of an escalation of fighting with al-Nusra.
Government offensives and Presidential election (March–June 2014)
On 4 March, the Syrian Army took control of Sahel in the Qalamoun region. On 8 March, government forces took over Zara, in Homs Governorate, further blocking rebel supply routes from Lebanon. On 11 March, Government forces and Hezbollah took control of the Rima Farms region, directly facing Yabrud. On 16 March, Hezbollah and government forces captured Yabrud, after Free Syrian Army fighters made an unexpected withdrawal, leaving the al-Nusra Front to fight in the city on its own. On 18 March, Israel used artillery against a Syrian Army base, after four of its soldiers had been wounded by a roadside bomb while patrolling Golan Heights.
On 19 March, the Syrian Army captured Ras al-Ain near Yabrud, after two days of fighting and al-Husn in Homs Governorate, while rebels in the Daraa Governorate captured Daraa prison, and freed hundreds of detainees. On 20 March, the Syrian Army took control of the Krak des Chevaliers in al-Husn. On 29 March, Syrian Army took control of the villages of Flitah and Ras Maara near the border with Lebanon.
On 22 March, rebels took control of the Kesab border post in the Latakia Governorate. By 23 March, rebels had taken most of Khan Sheikhoun in Hama. During clashes near the rebel-controlled Kesab border post in Latakia, Hilal Al Assad, NDF leader in Latakia and one of Bashar Al Assad's cousins was killed by rebel fighters. On 4 April, rebels captured the town of Babulin, Idlib. On 9 April, the Syrian Army took control of Rankous in the Qalamoun region. On 12 April, rebels in Aleppo stormed the government-held Ramouseh industrial district in an attempt to cut the Army supply route between the airport and a large Army base. The rebels also took the Rashidin neighbourhood and parts of the Jamiat al-Zahra district. On 26 April, the Syrian Army took control of Al-Zabadani. According to SOHR, rebels took control of Tell Ahrmar, Quneitra. Rebels in Daraa also took over Brigade 61 Base and the 74th battalion.
On 26 April, the FSA announced they had begun an offensive against ISIS in the Raqqa Governorate, and had seized five towns west of Raqqa city. On 29 April, activists said that the Syrian Army captured Tal Buraq near the town of Mashara in Quneitra without any clashes. On 7 May, a truce went into effect in the city of Homs, SOHR reported. The terms of the agreement include safe evacuation of Islamist fighters from the city, which would then fall under government control, in exchange for release of prisoners and safe passage of humanitarian aid for Nubul and Zahraa, two Shiite enclaves besieged by the rebels. On 18 May, the head of Syria's Air Defense, General Hussein Ishaq, died of wounds sustained during a rebel attack on an air defense base near Mleiha the previous day. In Hama Governorate, rebel forces took control of the town of Tel Malah, killing 34 pro-Assad fighters at an army post near the town. Its seizure marked the third time rebels have taken control of the town.
Syria held a presidential election in government-held areas on 3 June 2014. For the first time in the history of Syria more than one person was allowed to stand as a presidential candidate. More than 9,000 polling stations were set up in government-held areas. According to the Supreme Constitutional Court of Syria, 11.63 million Syrians voted (the turnout was 73.42%). President Bashar al-Assad won the election with 88.7% of the votes. As for Assad's challengers, Hassan al-Nouri received 4.3% of the votes and Maher Hajjar received 3.2%. Allies of Assad from more than 30 countries were invited by the Syrian government to follow the presidential election, including Bolivia, Brazil, Cuba, Ecuador, India, Iran, Iraq, Nicaragua, Russia, South Africa and Venezuela. The Iranian official Alaeddin Boroujerdi read a statement by the group saying the election was "free, fair and transparent". The Gulf Cooperation Council, the European Union and the United States all dismissed the election as illegitimate and a farce.
It is claimed in an opinion piece that as few as 6 million eligible voters remained in Syria. Due to rebel, Kurdish and ISIS control of Syrian territories there was no voting in roughly 60% of the country.
ISIL offensives and U.S. airstrikes (June 2014 – January 2015)
Starting on 5 June, ISIL seized swathes of territory in Iraq in addition to heavy weapons and equipment from the Iraqi Army, some of which they brought into Syria. Government airstrikes targeted ISIL bases in Raqqa and Al-Hasakah in coordination with an Iraqi Army counteroffensive. On 14 June, government forces retook the town of Kessab in northern Latakia Governorate, while rebels took over Tall al-Gomo near the town of Nawa in the Daraa Governorate, as well as reentering the Qalamoun area.
According to the Syrian Observatory for Human Rights, on 17 July ISIL took control of the Shaar oil field, killing 90 pro-government forces while losing 21 fighters. In addition, 270 guards and government-aligned fighters were missing. About 30 government persons managed to escape to the nearby Hajjar field. On 20 July, the Syrian Army secured the field, although fighting continued in its outskirts. On 25 July, the Islamic State took control of the Division 17 base near Raqqa.
On 7 August, ISIL took the Brigade 93 base in Raqqa using weapons captured from their offensive in Iraq. Multiple suicide bombs also went off before the base was stormed. On 13 August, ISIL forces took the towns of Akhtarin and Turkmanbareh from rebels in Aleppo. ISIL forces also took a handful of nearby villages. The other towns seized include Masoudiyeh, Dabiq and Ghouz.
On 14 August, the Free Syrian Army commander Sharif As-Safouri admitted working with Israel and receiving anti-tank weapons from Israel and FSA soldiers also received medical treatment inside Israel. On 14 August, the Syrian Army as well as Hezbollah militias retook the town of Mleiha in Rif Dimashq Governorate. The Supreme Military Council of the FSA denied claims of Mleiha's seizure, rather the rebels have redeployed from recent advances to other defensive lines. Mleiha has been held by the Islamic Front. Rebels had used the town to fire mortars on government held areas inside Damascus.
Meanwhile, ISIL forces in Raqqa were launching a siege on Tabqa airbase, the Syrian government's last military base in Raqqa. Kuwaires airbase in Aleppo also came under fierce attack by ISIL. On 16 August, there were reports that 22 people were killed in the village of Daraa by a car bomb outside a mosque. The bomb was thought to be detonated by ISIS. Also on 16 August, the Islamic State seized the village of Beden in Aleppo Governorate from rebels.
On 19 August, a senior figure in ISIL who had helped prepare and plan car and suicide bombs across Syria, Lebanon, and Iraq was killed. Some reports said that he was killed by Hezbollah fighters. There were also several reports that he was killed by the Syrian Army in the Qalamoun region, near the border with Lebanon.
On 19 August, American journalist James Foley was executed by ISIL, who claimed it was in retaliation for the United States operations in Iraq. Foley was kidnapped in Syria in November 2012 by Shabiha militia. ISIL also threatened to execute Steven Sotloff, who was kidnapped at the Syrian-Turkish border in August 2013. There were reports ISIS captured a Japanese national, two Italian nationals, and a Danish national as well. At least 70 journalists have been killed covering the Syrian war, and more than 80 kidnapped, according to the Committee to Protect Journalists.
On 23 August, the Tabqa airbase was no longer encircled by ISIL fighters and the Syrian Army had taken back the M-42 Highway from ISIL fighters, which leads to the city of Salamiyah in the Hama Governorate. Also in Raqqa, the Syrian Army took control of the town of Al-Ejeil. ISIL reportedly sent reinforcements from Iraq to the governorate of Raqqa. The Syrian Observatory for Human Rights said at least 400 ISIL fighters had also been wounded in the previous five days in clashes with the Syrian Army and National Defence Force in Raqqa alone. At the same time, several senior UK and US figures urged Turkey to stop allowing ISIL to cross the border to Syria and Iraq. It was around this time that the Americans realized that the Turks had no intention of sealing their side of the border, and so Washington decided to work with the Syrian Kurds to close off the border on the Syrian side. A year later, with the Kurds in control of most of the Turkey–Syria border, and the Syrian army advancing under Russian air support to seal the remainder, the situation was causing great ructions in Ankara.
On the following day, the Islamic State seized Tabqa airbase from government forces. The battle for the base left 346 ISIL fighters and 195 soldiers dead. Prisoners taken by ISIL forces were executed and a video from the mass killing was posted on YouTube. The death toll varied from 120 to 250.
On 26 August, the Syrian Air Force carried out airstrikes against ISIL targets in the Governorate of Deir ez-Zor. This was the first time the Syrian Army attacked them in Deir ez-Zor as the Syrian Army pulled out of Raqqa and shifted to Deir ez-Zor in a bid to seize its oil and natural gas resources as well as strategically splitting ISIL territories.
American jets began bombing ISIL in Syria on 23 September 2014, raising U.S. involvement in the war-torn country. At least 20 targets in and around Raqqa were hit, the opposition group Syrian Observatory for Human Rights said. Foreign partners participating in the strikes with the United States were Bahrain, Saudi Arabia, the United Arab Emirates, Qatar and Jordan. The U.S. and "partner nation forces" began striking ISIL targets using fighters, bombers and Tomahawk missiles, Pentagon spokesman Rear Adm. John Kirby said.
U.S. aircraft include B-1 bombers, F-16s, F-18s and Predator drones, with F-18s flying missions off the USS George H.W. Bush (CVN-77) in the Persian Gulf. Tomahawk missiles were fired from the destroyer USS Arleigh Burke (DDG-51) in the Red Sea. Syria's Foreign Ministry told the Associated Press that the U.S. informed Syria's envoy to the U.N. that "strikes will be launched against the terrorist group in Raqqa". The United States informed the Free Syrian Army beforehand of the impending airstrikes, and the rebels said that weapons transfers to the Free Syrian Army had begun.
The United States also attacked a specific faction of al-Nusra called the Khorasan Group, who according to the United States had training camps and plans for attacking the United States in the future.
For its part, Turkey launched an official request to the U.N. for a no-fly zone over Syria.
The same day, Israel shot down a Syrian warplane after it entered the Golan area from Quneitra.
Within 36 hours from 21 October, the Syrian air force carried out over 200 airstrikes on rebel-held areas across Syria and US and Arab jets attacked IS positions around Kobanî. Syrian Information Minister Omran al-Zoubi said the YPG forces in Kobanî had been provided with military and logistical support. Syria reported that its air force had destroyed two fighter jets being operated by IS.
By 26 January, the Kurdish YPG forced ISIL forces in Kobanî to retreat, thus fully recapturing the city. The U.S. confirmed that the city had been cleared of ISIL forces on 27 January, and ISIL admitted defeat in Kobanî city three days later, although they vowed to return.
The Southern Front (October 2014 – February 2015)
In February 2014, the Southern Front of the Free Syrian Army formed in southern Syria. Six months later, they started a string of victories in Daraa and Quneitra during the 2014 Quneitra offensive, the Daraa offensive, the Battle of Al-Shaykh Maskin, the Battle of Bosra (2015) and the Battle of Nasib Border Crossing. A government counter-offensive (the 2015 Southern Syria offensive) during this period, that included the IRGC and Hezbollah, recaptured 15 towns, villages and hills, but the operation slowed soon after and stalled.
Since early 2015, opposition military operations rooms based in Jordan and Turkey began increasing cooperation, with Saudi Arabia and Qatar also reportedly agreeing upon the necessity to unite opposition factions against the Syrian government.
Northern Al-Nusra Front and Islamist takeover (October 2014 – March 2015)
In late October 2014, a conflict erupted between the al-Nusra Front on one side and the western-backed SRF and Hazzm Movement on the other (Al-Nusra Front–SRF/Hazzm Movement conflict). ISIL reportedly reinforced al-Nusra. By the end of February 2015 al-Nusra had defeated both groups, captured the entire Zawiya Mountain region in Idlib province and several towns and military bases in other governorates, and seized weapons supplied by the CIA to the two moderate groups. The significant amount of weapons seized included a small number of BGM-71 anti-tank missiles similar to weapons systems al-Nusra Front had previously captured from government stockpiles such as French MILANs, Chinese HJ-8s and Russian 9K111 Fagots. Reuters reported that this represented al-Nusra crushing pro-Western rebels in the north of the country. According to FSA commanders in northern Syria, however, the elimination of Harakat Hazm and the SRF was a welcome development due to the leaders of those factions allegedly involved in corruption. The Western-backed 30th Division of the FSA remained active elsewhere in Idlib.
By 24 March 2015 the al-Nusra Front dominated most of Idlib province, except for the government-held provincial capital, Idlib, which they had encircled on three sides along with its Islamist allies. On 28 March a joint coalition of Islamist forces, the Army of Conquest, captured Idlib. This left the north largely taken over by Ahrar ash-Sham, al-Nusra Front and other Islamist rebels, with the south of the country becoming the last significant foothold for the mainstream, non-jihadist opposition fighters.
Army of Conquest advances in Idlib (April 2015 – June 2015)
On 22 April, a new rebel offensive was launched in the north-west of Syria and by 25 April, the rebel coalition Army of Conquest had captured the city of Jisr al-Shughur. At the end of the following month, the rebels also seized the Al-Mastumah military base, and Ariha, leaving government forces in control of tiny pockets of Idlib, including the Abu Dhuhur military airport. In addition, according to Charles Lister (Brookings Doha Center), the Army of Conquest coalition was a broad opposition effort to ensure that the Al-Qaeda-affiliated al-Nusra Front was contained, with the rearguard involvement of Western-backed factions being regarded as crucial. Still, according to some, the FSA in northern Syria had by this point all but dissipated. Many of the moderate fighters joined more extremist organizations, such as Ahrar ash-Sham, the largest faction in the Army of Conquest, which led to the subsequent rise of the Islamist Army of Conquest coalition.
Rebel advances led to government and Hezbollah morale plunging dramatically. In north-west Syria these losses were countered by a Hezbollah-led offensive in the Qalamoun mountains north of Damascus, on the border with Lebanon, that gave Hezbollah effective control of the entire area.
Resurgent ISIL advance (May 2015 – September 2015)
On 21 May, ISIL took control of Palmyra, a UNESCO World Heritage Site, after eight days of fighting. The jihadists also captured the nearby towns of Al-Sukhnah and Amiriya, as well as several oil fields. Following the capture of Palmyra, ISIL conducted mass executions in the area, killing an estimated 217–329 government civilian supporters and soldiers, according to opposition activists. Government sources put the number of killed at 400–450.
By early June, ISIL reached the town of Hassia, which lies on the main road from Damascus to Homs and Latakia, and reportedly took up positions to the west of it, creating a potential disaster for the government and raising the threat of Lebanon being sucked further into the war.
On 25 June, ISIL launched two offensives. One was a surprise diversionary attack on Kobanî, while the second targeted government-held parts of Al-Hasakah city. The ISIL offensive on Al-Hasakah displaced 60,000 people, with the UN estimating a total of 200,000 would be displaced.
In July 2015, a raid by U.S. special forces on a compound housing the Islamic State's "chief financial officer", Abu Sayyaf, produced evidence that Turkish officials directly dealt with ranking ISIS members.
Australia joined the bombing of ISIL in Syria in mid September, an extension of their efforts in Iraq for the last year.
Russian intervention and government offensive (30 September 2015–February 2016)
|Russian military facilities involved in the war in Syria|
On 30 September 2015, at an official request by the Syrian government headed by President Bashar al-Assad, the Russian Aerospace Forces began a sustained campaign of air strikes against both ISIL and the anti-Assad FSA. Initially, the raids were conducted solely by Russian aircraft stationed in the Khmeimim base in Syria. Shortly after the start of the Russian operation, U.S. president Barack Obama was reported to have authorized the resupply of Syrian Kurds and the Arab-Syrian opposition, Obama reportedly emphasizing to his team that the U.S. would continue to support the Syrian opposition now that Russia had joined the conflict.
On 7 October 2015, Russian officials said the ships of the Caspian Flotilla had earlier that day fired 26 sea-based cruise missiles at 11 ISIL targets in Syria destroying those and causing no civilian casualties. On the same day, the Syrian government′s ground forces launched a ground offensive that in the following few days succeeded in recapturing some territory in northern Hama Governorate, close to the government's coastal heartland in the west of the country.
On 8 October 2015, the U.S. officially announced the end of the Pentagon’s $500 million program to train and equip Syrian rebels in an acknowledgment that the program had failed (other covert and significantly larger CIA programs to arm anti-government fighters in Syria continue).
Two weeks after the start of the Russian campaign in Syria, The New York Times opined that with anti-government commanders receiving for the first time bountiful supplies of U.S.-made anti-tank missiles and with Russia raising the number of airstrikes against the government’s opponents that had raised morale in both camps, broadening war objectives and hardening political positions, the conflict was turning into an all-out proxy war between the U.S. and Russia.
Despite multiple top-ranking casualties incurred by the Iranian forces advising fighters in Syria, in mid-October the Russian-Syrian-Iranian-Hezbollah offensive targeting rebels in Aleppo went ahead.
At the end of October 2015, the U.S. Secretary of Defense Ashton Carter signalled a shift in the strategy of the U.S.-led campaign saying there will be more air strikes and ruling in the use of direct ground raids, the fight in Syria concentrating mostly on Raqqa.
On 30 October and two weeks later, Syria peace talks were held in Vienna, initiated by the United States, Russia, Turkey and Saudi Arabia, in which on 30 October Iran participated for the first time in negotiations on Syrian settlement. The participants disagreed on the future of Bashar Assad.
On 10 November 2015, the Syrian government forces completed the operation to break through the Islamic State insurgents′ blockade of the Kweires air base in Aleppo Province, where government forces had been under siege since April 2013.
In mid-November 2015, in the wake of the Russian plane bombing over Sinai and the Paris attacks, both Russia and France significantly intensified their strikes in Syria, France closely coordinating with the U.S. military. On 17 November, Putin said he had issued orders for the cruiser Moskva that had been in eastern Mediterranean since the start of the Russian operations to "work as with an ally", with the French naval group led by flagship Charles De Gaulle that had been on her way to eastern Mediterranean since early November. Shortly afterwards, a Russian foreign ministry official criticised France′s stridently anti-Assad stance as well as France′s air strikes at oil and gas installations in Syria as apparently designed to prevent those from returning under the Syrian government′s control; the Russian official pointed out that such strikes by France could not be justified as they were carried out without the Syrian government′s consent. In his remarks to a French delegation that included French parliamentarians, on 14 November, President Bashar Assad sharply criticised France′s as well as other Western States′ actions against the Syrian government suggesting that French support for Syrian opposition forces had led to the Islamic State-claimed attacks in Paris.
On 19 November 2015, U.S. President Barack Obama, speaking of the Vienna process, said he was unable to "foresee a situation in which we can end the civil war in Syria while Assad remains in power"; he urged Russia and Iran to stop supporting the Syrian government.
On 20 November 2015, the UN Security Council, while failing to invoke the UN's Chapter VII, which gives specific legal authorisation for the use of force, unanimously passed Resolution 2249 that urged UN members to "redouble and coordinate their efforts to prevent and suppress terrorist acts committed specifically by ISIL also known as Da’esh as well as ANF, and all other individuals, groups, undertakings, and entities associated with Al-Qaida, and other terrorist groups, as designated by the United Nations Security Council, and as may further be agreed by the International Syria Support Group (ISSG) and endorsed by the UN Security Council". The adopted resolution was drafted by France and co-sponsored by the UK the following day after Russia introduced an updated version of its previously submitted draft resolution that was blocked by the Western powers as seeking to legitimise Assad’s authority.
On 24 November 2015, Turkey shot down a Russian warplane that allegedly violated Turkish airspace and crashed in northwestern Syria, leading to the Russian pilot's death. Following the crash, it was reported that Syrian Turkmen rebels from Syrian Turkmen Brigades attacked and shot down a Russian rescue helicopter, killing a Russian naval infantryman. A few days after, Russian aircraft were reported to have struck targets in the Syrian town of Ariha in Idlib province that was controlled by the Army of Conquest causing multiple casualties on the ground.
On 2 December 2015, the Parliament of the United Kingdom voted to expand Operation Shader into Syria with a majority of 397-223. That day, two British Tornado aircraft took off from RAF Akrotiri immediately at 22:30, each carrying three Paveway bombs. Two further aircraft were deployed at 00:30 on 3 December, and all aircraft returned by 06:30 without their bombs. Defence Secretary Michael Fallon said that the strikes hit the Omar oil fields in eastern Syria, and that eight more jets (two Tornados and six Typhoons) were being sent to RAF Akrotiri to join the eight already there.
On 7 December 2015, the government of Syria announced that US-led coalition warplanes had fired nine missiles at its army camp near Ayyash, Deir al-Zour province, on the evening prior, killing three soldiers and wounding 13 others; three armoured vehicles, four military vehicles, heavy machine-guns and an arms and ammunition depot were also destroyed. The government condemned the strikes, the first time the government forces would be struck by the coalition, as an act of "flagrant aggression"; the coalition spokesman denied it was responsible. Anonymous Pentagon officials alleged later in the day that the Pentagon was "certain" that a Russian warplane (presumably a TU-22 bomber) had carried out the attack. The claim was denied by the Russian military spokesman who noted that four Western coalition warplanes (other than U.S.) had been spotted over the Deir az-Zor area in Syria on 6 December.
The UN resolution 2254 of 18 December 2015 that endorsed the ISSG′s transitional plan but did not clarify who would represent the Syrian opposition, while condemning terrorist groups like ISIL and al-Qaeda; it made no mention of the future role of Syrian President Bashar Assad.
On 12 January 2016, the Syria government announced that its army and allied forces had established "full control" of the strategically situated town of Salma, whose pre-war population was predominantly Sunni, in the northwestern province of Latakia, and continued to advance north.
On 16 January 2016, ISIL militants launched raid on government-held areas in the city of Deir ez-Zor and killed up to 300 people. Counter-strikes by Russian Air Force fighter jets, in support of Syrian army forces, were reported to take back the areas.
On 21 January 2016, Russia′s activity presumably aimed at setting up a new base in the government-controlled Kamishly Airport was first reported; the northeastern town of Qamishli in the Al-Hasakah Governorate had been largely under the Syrian Kurds′ control since the start of the Syrian Kurdish–Islamist conflict in the governorate of Al-Hasakah in July 2013. Similar activity by the U.S. forces was suspected in the Rmeilan Airbase in the same province, 50 km away from the Kamishly Airport; the area is likewise controlled by the US-backed Kurdish People's Protection Units (YPG).
On 24 January 2016, the Syrian government announced its forces, carrying on with their Latakia offensive, had seized the predominantly Sunni-populated town of Rabia, the last major town held by rebels in western Latakia province; Russian forces were said to have played an important role in the recapture. The capture of Rabia was said to threaten rebel supply lines from Turkey.
By 26 January 2016, the Syrian government established "full control" over the town of Al-Shaykh Maskin in the Daraa Governorate, thus completing the operation that had begun in late December 2015. The town′s capture by the Syrian government was remarked as a "turning of the tide in the Syrian war" by Al-Jazeera.
Partial ceasefire (from 26 February–July 2016)
On 26 February 2016, the United Nations Security Council unanimously adopted resolution 2268 that demanded all parties to comply with the terms of a U.S.-Russian deal on a "cessation of hostilities". The cease-fire started on 27 February 2016 at 00:00 (Damascus time). The ceasefire does not include attacks on UN-designated terrorist organizations. At the close of February 2016, despite individual clashes, the truce was reported to hold. By the end of March, the Syrian government forces with support from Russia and Iran successfully captured Palmyra from the ISIL.
By early July 2016, the truce was said to have mostly unraveled, and the fighting between all the major parties to the conflict continued. At the end of July 2016, the fighting between the government and Islamist rebels in and around Aleppo intensified.
Kurdish advances and Turkish military intervention (August 2016–present)
On 12 August 2016, the Syrian Democratic Forces fully captured Manbij from ISIL. Some days later the SDF announced a new offensive towards Al-Bab, which could eventually connect the Kurdish regions in Northern Syria.
A few days after, the battle of al-Hasakah began. On 22 August, the Kurdish YPG, having captured Ghwairan, the only major Arab neighbourhood in Hasaka that had been in government hands, launched a major assault to seize the last government-controlled areas of the northeastern Syrian city of Hasaka, after a Russian mediation team failed to mend the rift between the two sides; the next day the capture of the city was completed. A few days prior, the Pentagon admonished the Syrian government against "interfering with coalition forces or our partners" in that region, adding that the U.S. had the right to defend its troops.
On 24 August 2016, Turkey′s armed forces invaded Syria in the Jarabulus area controlled by ISIL starting what the Turkish president called the Operation Euphrates Shield, aimed against, according to his statement, both the IS and Kurdish ″terror groups that threaten our country in northern Syria″. The Syrian government denounced the intervention as a "blatant violation of its sovereignty" and said that "fighting terrorism isn’t done by ousting ISIS and replacing it with other terrorist organizations backed directly by Turkey". The PYD leader Salih Muslim said that Turkey was now in the "Syrian quagmire" and would be defeated like IS. Speaking in Ankara the same day, US vice president Joe Biden indirectly endorsed Turkey′s move and said that the U.S. had made it clear to the Syrian Kurdish forces that they should move back east across the Euphrates, or lose US support.
As Turkish troops and the Turkish-aligned Syrian rebels took control of Jarablus and moved further south towards the Syrian town of Manbij, they clashed with the Kurdish YPG, which led the U.S. officials to voice concern and issue a warning to both sides. On 29 August, U.S. Defense Secretary Ashton Carter specified that the U.S. did not support Turkey′s advance south of Jarablus. The warning as well as an announcement made by the U.S. of a tentative ceasefire between the Turkish forces and the Kurds in the area of Jarablus were promptly and angrily dismissed by Turkey′s officials. However, combat between the Turkish forces and the SDF died down, and instead Turkish forces moved West to confront IS. In the meantime the SDF, including Western volunteers, continued to reinforce Manbij.
At sunset on 12 September 2016, a U.S.-Russian brokered cease-fire came into effect. Five days later, the U.S. and other coalition members′ jets bombed Syrian Army positions near Deir ez-Zor—purportedly by accident, but with Russia contending that it was intentional—killing at least 62 Syrian troops that were fighting ISIL militants. Shortly after, the ceasefire broke down, and on 19 September the Syrian Army declared to no longer observe the truce. Also on 19 September, an aid convoy in Aleppo was attacked with the U.S. coalition blaming the Russian and Syrian governments for the attack and these same governments denying these accusation and instead blaming terrorists for the attack.
