Foreign involvement in the Syrian civil war
Foreign involvement in the Syrian civil war refers to political, military and operational support to parties involved in the Syrian civil war, as well as to incidents of unintentional foreign involvement. The Syrian civil war has received significant international attention, and both the Syrian government and the opposition have received support, militarily, logistically and diplomatically, from foreign countries.
The main Syrian opposition body - the Syrian coalition - receives logistic and political support from major Sunni states in the Middle East, most notably Turkey, Qatar and Saudi Arabia. France, Britain and thd US have also provided political, military and logistic support to the opposition. The major Syrian Kurdish opposition group, the PYD, was reported to get logistic and training support from Iraqi Kurdistan. Islamist militants in Syria were reported to receive support from private funders, mainly from the Persian Gulf area, as well as from Iraqi ISIL.
The Syrian government is supported by Iran and Hezbollah, both involved in the war politically, logistically and militarily. Hezbollah fields soldiers in the conflict. The Syrian government also receives arms and political support from Russia. Some support for Syrian Baathist government was received from North Korea, Venezuela, China and Huthi rebels of Yemen.
The Syrian civil war has spilled across its borders and most notably affected Lebanon, where the sectarian violence related to the Syrian war has already resulted in more than 200 deaths; the incidents mostly include infighting between Lebanese Sunnis and Alawites, as well as violence between Hezbollah and Syrian rebel-affiliated groups near the Syrian-Lebanese border. The Syrian Army has also performed a number of strikes on Lebanese territory against Syrian rebel-affiliated targets. During 2013, the violence of Syrian civil war has begun to increasingly penetrate Iraq, some describing the result as merger of Iraqi insurgency) and Syrian civil war - both conflicts between Sunnis and Shias, with Iraqi Jihadists engaging in fights with Syrian Army in border areas. A number of alleged strikes against Hezbollah and Iranian targets within Syrian territory during 2013 were attributed to Israel. Incidents involving the Syrian Army and Syrian rebels also took place on Jordanian, Israeli and most significantly Turkish borders with Syria.

Support for the opposition
France and Britain
On 1 November 2011, NATO said it had no intention of taking military action in Syria, after it closed its seven-month campaign in Libya. On that same month, Libyan rulers offered weapons, money and potential volunteers, it was reported that 600 rebel fighters have gone from Libya to Syria in order to support the rebels.
In June 2012, Reuters suggested that the prospect of British special forces entering Syria on the ground is growing, following unconfirmed reports from an Israeli website that SAS Commandos were conducting covert operations within Syrian territory, operating from Turkey on 26 June 2012.
At a conference in Paris in July 2012, Western and Sunni Arab countries nonetheless announced they were going to "massively increase" aid to the Syrian opposition.
In 2012, the United States, United Kingdom and France provided opposition forces with non-lethal military aid, including communications equipment and medical supplies. The U.K. was also reported to have provided intelligence support from its Cyprus bases, revealing Syrian military movements to Turkish officials, who then pass on the information to the FSA.
A crucial line of support began in spring 2012 as Saudi Arabia and Qatar announced they would begin arming and bankrolling the opposition. Paul Salem, director of the Carnegie Middle East Centre in Beirut, and Emile Hokayem of the International Institute of Strategic Studies argued such support would be unlikely to immediately make a decisive impact. A ship carrying weapons from Libya believed destined for Syria's rebels has also been intercepted. Qatar is reported to be shipping arms to Sunni Islamists in Syria as a means of cementing alliances in the Middle East.
On 22 April 2013 the European Union lifted its embargo on Syrian oil to import barrels directly from rebel groups. Several of the oil fields are believed to be under control of Jabhat al-Nusra. Some analysts say the decision might also set up a deadly competition between rebel groups over the resource.
In late August 2013 a number of commercial pilots and local residents have reported seeing increased numbers of British military aircraft at RAF Akrotiri including C-130 transports and fighter aircraft.
A vote was held within the British House of Commons on 29 August 2013 to decide whether the United Kingdom would join the United States in initiating militant action against the use of chemical weapons by the Syrian Government. Despite support from the Prime Minister David Cameron, the motion was defeated by 285 votes to 272. Cameron said that he would respect this Parliamentary decision and that the United Kingdom would not partake in military action against Syria.
On 19 September 2013, French President François Hollande hinted that France was ready to begin supplying lethal aid to the Free Syrian Army during a press conference in Bamako in a "controlled framework". Hollande told the conference that "On delivering weapons we have always said that we want to control these supplies so that they do indeed go to the Free Syrian Army ... because they represent the Syrian National Coalition that we recognise as the legitimate representative of the Syrian people and today they are caught between a hammer and an anvil. The hammer is the air strikes and actions of the Syrian regime and the anvil is radical Islam.”
In June 2012, the Central Intelligence Agency was reported to be involved in covert operations along the Turkish-Syrian border, where agents investigated rebel groups, recommending arms providers which groups to give aid to. Agents also helped opposition forces develop supply routes, and provided them with communications training. CIA operatives distributed assault rifles, anti-tank rocket launchers and other ammunition to Syrian opposition. The State Department has reportedly allocated $15 million for civilian opposition groups in Syria.
In early March 2013, a Jordanian security source revealed that the United States, Britain, and France were training non-Islamist rebels in Jordan. In April 2013, also in Jordan, the United States had set up a $70 million program in the country "that is training the kingdom’s special forces to identify and secure chemical-weapons sites across Syria should the regime fall and the wrong rebels look like getting their hands on them."
In April 2013, the Obama administration promised to double non-lethal aid to rebels, specifically to $250 million.
On 13 June, government officials state that the Obama administration, after days of high-level meetings, has approved providing lethal arms to the Supreme Military Council (SMC). The SMC is a rebel command structure that includes representatives from most major rebel groups, and excludes the Islamic extremist elements. The decision was made shortly after the administration has concluded that the Assad government has used chemical weapons on opposition forces, thus crossing the "red line" drawn by Obama earlier in 2012. The arms will include small arms and ammunition, and possibly anti-tank weapons. However, they will not include anti-aircraft weapons, something repeatedly requested by the armed opposition. Further such weapons would be supplied by the US "on our own timeline". The United States is also considering a no-fly zone in southern Syria, which would allow a safe place to equip and train rebels.
On August 26, the United States deployed ships near Syria amidst a United Nations investigation concerning allegations that Syrian president al-Assad used chemical weapons against civilians. The following ships were deployed: USS Barry, USS Gravely, USS Mahan, and USS Ramage.
In a speech given on August 31, 2013, President Obama asked the United States Congress to authorize direct American military intervention in the civil war. The United States Senate Committee on Foreign Relations approved the Authorization for the Use of Military Force Against the Government of Syria to Respond to Use of Chemical Weapons (S.J.Res 21) on September 4, 2013. The bill would have allowed the president to take direct action for up to 90 days; it specifically forbid putting "boots on the ground." While it was bring debated, Russia urged Syria to put its' chemical weapons stockpile under international control. On September 14, US and Russia announced in Geneva that they reached a deal on how Assad should give up his chemical weapons.
During September 2013, it was reported by US officials that under "a covert CIA program" small arms fire and anti tank weapons had begun reaching some moderate rebel groups. Although Free Syrian Army Commander Salim Idriss denied receiving lethal aid, some analysts commented that information on US arms may not have reached Idriss due to poor communications as the Free Syrian Army command was based in Northern Syria whilst weapons were reportedly reaching rebel groups in the south.
The Financial Times reported that Qatar had funded the Syrian rebellion by "as much as $3 billion" over the first two years of the civil war. It reported that Qatar was offering refugee packages of about $50,000 a year to defectors and family.
The Financial Times reported in May 2013 that Saudi Arabia was becoming a larger provider of arms to the rebels. Since the summer of 2013, Saudi Arabia has emerged as the main group to finance and arm the rebels. Saudi Arabia has financed a large purchase of infantry weapons, such as Yugoslav-made recoilless guns and the M79 Osa, an anti-tank weapon, from Croatia via shipments shuttled through Jordan. The weapons began reaching rebels in December 2012 which allowed rebels' small tactical gains this winter against the army and militias loyal to Assad. This was to counter shipments of weapons from Iran to Assad's forces.
Bashar al-Assad pointed at Saudi Arabia as the major supporter of terrorists and "leading the most extensive operation of direct sabotage against all the Arab world".
In December 2012, a new wave of weapons from foreign supporters were transferred to rebel forces via the Jordanian border in the country's south. The arms included M79 Osa anti-tank weapons and M-60 recoilless rifles purchased by Saudi Arabia from Croatia. Previously, most of the weapons were delivered via the Turkish border in the north. However, much of the arms unintentionally ended up in the hands of Islamist rebels. The goal for the change in routes was to strengthen moderate rebels and to bring the war closer to Damascus.
According to Jutarnji list, a Croatian daily newspaper, there were an unusually high number of sightings of Ilyushin 76 aircraft owned by Jordan International Air Cargo at Pleso Airport in Zagreb, Croatia on December 14 and 23, 2012; January 6; and February 18, 2013. In early January 2013, Yugoslav weapons were seen used in battles in the Dara'a region near Jordan. Then, in February 2013, Yugoslav weapons were seen in videos posted by rebels fighting in the Hama, Idlib, and Aleppo regions. Danijela Barisic of Croatia's Foreign Ministry and arms-export agency denied that such shipments had occurred. Saudi officials have declined requests for interviews about the shipments for two weeks. Ukrainian-made rifle cartridges, Swiss-made hand grenades, Belgian-made rifles are showing up in the rebels hands but the origin is not clear because Saudi Arabia has insisted on secrecy.
Bandar bin Sultan
In August 2013 the Wall Street Journal reported that Saudi Prince Bandar bin Sultan had been appointed to lead Saudi Arabia's efforts to topple Syrian President Bashar al-Assad, and that the US Central Intelligence Agency considered this a sign of how serious Saudi Arabia was about this aim. Bandar was described as "jetting from covert command centers near the Syrian front lines to the Élysée Palace in Paris and the Kremlin in Moscow, seeking to undermine the Assad regime." After tensions with Qatar over supplying rebel groups, Saudi Arabia switched its efforts from Turkey to Jordan in 2012, using its financial leverage over Jordan to develop training facilities there, overseen by Bandar's half-brother Salman bin Sultan. In late 2012 Saudi intelligence also began efforts to convince the US that the Assad government was using chemical weapons. The Saudi government also would be sending sentenced to death for Jihad in Syria. 
Sunni Arab states are concerned that the Iranian arms transfers are changing the balance of power in the region and has "become a regional contest for primacy in Syria between Sunni Arabs and the Iran-backed Assad government and Hezbollah of Lebanon." Iran is using the Maharaj Airlines to ship weapons to Syrian government.
On 6 March 2013, the Arab League gave its members the "green light" to arm the Syrian rebels. On 26 March 2013, at the Arab league summit in Doha, the League recognised the National Coalition for Syrian Revolutionary and Opposition Forces, as the legitimate representatives of the Syrian people.
Turkey, whose relations with Syria had been friendly over the last decade, condemned Assad over the violent crackdown and has requested his departure from office. Turkey trained defectors of the Syrian Army on its territory, and in July 2011 a group of them announced the birth of the Free Syrian Army under the supervision of Turkish military intelligence. In October 2011, Turkey began sheltering the Free Syrian Army, offering the group a safe zone and a base of operation.Together with Saudi Arabia and Qatar, Turkey has also provided the rebels with arms and other military equipment. Tensions between Syria and Turkey significantly worsened after Syrian forces shot down a Turkish fighter jet in June 2012 and border clashes in October 2012.
Turkey provided refuge for Syrian dissidents. Syrian opposition activists convened in Istanbul in May to discuss regime change, and Turkey hosts the head of the Free Syrian Army, Colonel Riad al-Asaad. Turkey has become increasingly hostile to the Assad government's policies and has encouraged reconciliation among dissident factions. Recep Tayyip Erdoğan has been trying to "cultivate a favorable relationship with whatever government would take the place of Assad." Beginning in May 2012, some Syrian opposition fighters began being armed and trained by the Turkish Intelligence.
Turkey maintains a small enclave within Syria itself, the Tomb of Suleyman Shah on the right bank of the Euphrates in Aleppo Province near the village of Qarah Qawzak (Karakozak). The Tomb is guarded by a small permanent garrison of Turkish soldiers, who rotate in from a battalion based at the Turkish border some 25 kilometres (16 mi) away—even as the civil war unfolded around them. Up until Syrian forces shot down a Turkish warplane in June 2012, the garrison numbered 15 men in total. Following the incident, the Turkish government doubled the number of soldiers stationed at the tomb to 30, while Prime Minister Erdoğan warned that "the tomb of Suleyman Shah and the land that surrounds it are Turkish territory. Any act of aggression against it would be an attack on our territory and NATO territory." Analysts have cited the Tomb as a potential future flashpoint in Turkish-Syrian relations.
There have been a number of foreign fighters that have joined the Syrian civil war in opposition to Assad. While some are jihadists, others, such as Mahdi al-Harati, have joined to help the Syrian revolution. Some fighters have come from as far away as Chechnya and Tajikistan. Another group, the Al-Nusra Front, is headed by Abu Muhammad al-Julani The group includes some of the rebellion's most battle-hardened and effective fighters. However, U.S. has formally designated the Al Nusra Front as a foreign terrorist organization. "Extremist groups like Jabhat al-Nusra are a problem, an obstacle to finding the political solution that Syria's going to need," said the American ambassador to Syria, Robert Ford.
Al-Qaeda and affiliates are anti-Assad. American officials believe that Al-Qaeda in Iraq has conducted bomb attacks against government forces, and al-Qaeda leader Ayman al-Zawahiri condemned Assad. Several groups, such as the Abdullah Azzam Shaheed Brigade, al-Nusra Front and Fatah al-Islam have stated that they conducted operations in Syria. Jihadist leaders and intelligence sources said foreign fighters had begun to enter Syria only in February 2012. In May 2012, Syria's U.N. envoy Bashar Ja'afari declared that dozens of foreign fighters from Libya, Tunisia, Egypt, Britain, France and elsewhere had been captured or killed, and urged Saudi Arabia, Qatar and Turkey to stop "their sponsorship of the armed rebellion". In June, it was reported that hundreds of foreign fighters, many linked to al-Qaeda, had gone to Syria to fight against Assad. In July, Iraq's foreign minister again warned that members of al-Qaeda in Iraq were seeking refuge in Syria and moving there to fight. When asked if the United States would arm the opposition, Hillary Clinton expressed fears that such weapons could fall into the hands of al-Qaeda or Hamas. In October 2012, the United States expressed concern and confirmed that most of the weapons fall into the hands of radical Islamist rebels.
In an interview with the Abkhazian News Agency Anna, a senior Syrian government official made allegations that former members of the Kosovo Liberation Army were fighting in Syria with the opposition. Reuters reported that a French doctor who worked clandestinely for 2 weeks in a besieged Aleppo hospital has said that over 50% of rebel fighters attended by him in Aleppo had been non-Syrian, in stark contrast with his experience in Homs and Idlib.
- Free Iraqi Army
In the western Sunni-majority provinces of Iraq, soldiers and war supplies have been crossing from Anbar Province into Syria. Armed groups inside Iraq have formed a Free Iraqi Army and have been supportive of the Syrian uprising against the Syrian government.
A rebel leader also claimed that the Israelis had many agents in Syria.
Support for the Syrian government
Russia, whose Tartus naval base in Syria is its only one outside the former Soviet Union, has supplied Assad's government with arms as part of a business contract signed before the uprising began. Russia has also sent military and technical advisers to train Syrian soldiers to use the Russian-made weapons and to help repair and maintain Syrian weapons. Western diplomats have frequently criticized Russia's behavior, but Russia denied its actions have violated any international law. Russian president Vladimir Putin has claimed that Russia does not support either side. Investigations by reporters also suggest that Russia is helping to keep the Syrian economy afloat by transporting hundreds of tonnes of banknotes into the country by airplane.
A joint group of 10 Russian warships and an equal number of escort vessels led by an anti-submarine destroyer and including landing ships with marines on board, entered the Mediterranean in late July. The task force has been deployed at the time of escalating fighting in Syria with the United States avowing to "intensify" its efforts "outside the Security Council". In July 2012, Vice-Adm. Viktor Chirkov made the statement that should the base come under attack, the Russian base would be forced to evacuate.
In December 2012, it was reported that "Russian military advisers" were inside Syria, manning some of the anti-aircraft defenses sent by Russia.
Iran and Syria are close strategic allies, and Iran has provided significant support for Syria in the Syrian civil war. This is said to include technical support, some combat troops, and $9bn in financial support. Iran's supreme leader, Ali Khamenei, was reported in September 2011 to be vocally in favor of the Syrian government. The Syrian city of Zabadani is vitally important to Assad and to Iran because, at least as late as June 2011, the city served as the Iranian Revolutionary Guard Corps's logistical hub for supplying Hezbollah.
In the civil uprising phase of the Syrian civil war, Iran was said to be providing Syria with technical support based on Iran's capabilities developed following the 2009–2010 Iranian election protests. As the uprising developed into the Syrian civil war, there were increasing reports of Iranian military support, partly in response to reports of increasing military support to the Syrian opposition from Gulf states.
23 and 24 February 2011, Lebanese Military Intelligence agents arrested six members of one Syrian family after they distributed flyers in Lebanon calling for protests against the Syrian regime. 25 February, one of them with two of his brothers vanished in Lebanon without leaving a trace. Human Rights Watch feared that Lebanon is back shutting up Syrian critics, perhaps forcibly transferring them to Syria.
Hezbollah has long been an ally of the Ba'ath Party government of Syria, led by the Al-Assad family. Hezbollah has allegedly helped the Syrian government in its fight against the armed Syrian opposition. In August 2012, the United States sanctioned Hezbollah for its alleged role in the war. Hezbollah leader Hassan Nasrallah denied Hezbollah had been fighting on behalf of the Syrian government, stating in a 12 October 2012 speech that "right from the start the Syrian opposition has been telling the media that Hizbullah sent 3,000 fighters to Syria, which we have denied". However, he said that Hezbollah fighters have gone to Syria independently and died there doing their "jihadist duties". Hezbollah states it supports a process of reforms in Syria and is against what it calls US plots to destabilize and interfere in Syria.
In January–February 2012, Hezbollah fighters allegedly helped the regime fight the rebels in Damascus and in the Battle of Zabadani. Later that year, Hezbollah fighters crossed the border from Lebanon and took over eight villages in the Al-Qusayr District of Syria. According to the Lebanese Daily Star newspaper, Nasrallah said that Hezbollah fighters helped the Syrian government "retain control of some 23 strategically located villages [in Syria] inhabited by Shiites of Lebanese citizenship". In September 2012, Hezbollah's commander in Syria, Ali Hussein Nassif, was killed along with several other Hezbollah militants in an ambush by the Free Syrian Army (FSA) near Al-Qusayr.
On 16–17 February 2013, Syrian opposition groups claimed that Hezbollah, backed by the Syrian military, attacked three FSA-controlled Sunni villages in Al-Qusayr. An FSA spokesman said, "Hezbollah's invasion is the first of its kind in terms of organisation, planning and coordination with the Syrian regime's air force". Hezbollah said three Lebanese Shias, "acting in self-defense", were killed in the clashes with the FSA. Lebanese security sources said that the three were Hezbollah members. In response, the FSA allegedly attacked two Hezbollah positions on 21 February; one in Syria and one in Lebanon. Five days later, it said it destroyed a convoy carrying Hezbollah fighters and Syrian officers to Lebanon, killing all the passengers. The leaders of the March 14 alliance and other prominent Lebanese figures called on Hezbollah to end its involvement in Syria and said it is putting Lebanon at risk. Subhi al-Tufayli, Hezbollah's former leader, said "Hezbollah should not be defending the criminal regime that kills its own people and that has never fired a shot in defense of the Palestinians". He said "those Hezbollah fighters who are killing children and terrorizing people and destroying houses in Syria will go to hell". The Consultaive Gathering, a group of Shia and Sunni leaders in Baalbek-Hermel, also called on Hezbollah not to "interfere" in Syria. They said "Opening a front against the Syrian people and dragging Lebanon to war with the Syrian people is very dangerous and will have a negative impact on the relations between the two". Walid Jumblatt, leader of the Progressive Socialist Party, also called on Hezbollah to end its involvement and claimed that "Hezbollah is fighting inside Syria with orders from Iran".
The Jerusalem Post reported that protesters in Syria, enraged at Hezbollah's support for the Assad regime, have burnt Hezbollah flags and images of Nasrallah, while pro-government protesters have carried posters of Nasrallah.
According to the US, the Assad loyalist militia known as Jaysh al-Sha'bi was created and is maintained by Hezbollah and Iran's Revolutionary Guard, both of whom provide it with money, weapons, training and advice. Also, according to Israeli intelligence sources, Hizbullah is working to forge loyalist regime militias into a 100,000-strong irregular army to fight alongside the regimes conventional forces.
In February 2012, it was reported that Hugo Chávez's government in Venezuela had been shipping tens of millions of dollars of diesel to Syria, which can be used to fuel army tanks. The following month, as it prepared a third shipment, Venezuela confirmed that it would continue sending diesel to the country. The Wall Street Journal obtained documents showing that a fourth big shipment of diesel was being readied in July 2012: "the deals are structured to bring other benefits, including shielding Syria's dwindling foreign-exchange reserves". The paper also noted that even "Syria's political opposition is split on the issue of cutting off all energy exports to the country. While they would like to see Mr. Assad's tanks run out of fuel, they also worry that a shortage of diesel could equally undermine the political and military opposition inside Syria." Chávez openly expressed his support for Assad's government while he was alive.
- North Korea (DPRK)
On 21 September 2012, Iraqi officials stated that they had refused a North Korean plane suspected of carrying weapons entry into Iraqi airspace en route to Syria. Earlier in the year, a UN probe was launched into North Korean arms deals with Syria and Myanmar in violation of international sanctions. The probe confirmed that North Korea was continuing to supply arms to Syria and Myanmar despite strict sanctions imposed in 2006 and 2009, using "elaborate techniques" to avoid interception. According to the report, one such "shipment originated in the DPRK, was trans-shipped in Dalian (China), and Port Klang (Malaysia), and transited through other ports... en route to Latakia, Syria." Illegal shipments were apparently not halted by the outbreak of war in Syria: according to a November 2012 report, a Chinese-registered ship containing North Korean missile parts, made in Cheongjin, bound for Syria was seized by South Korean authorities in May 2012.
Other reports suggest that dozens of Arabic-speaking Korean People's Army officers have aided planning of military operations and have supervised artillery bombardments in the Aleppo area. The Syrian Observatory for Human Rights claimed that 15 North Korean pilots operate combat helicopters in the country.
China vetoed a proposed UN Security Council resolution in tandem with Russia. Jerusalem Post correspondent Oren Kessler reported that Beijing's veto was enacted in the interests of preserving its ties with Russia. In September 2012, China announced that it was "impartial" on the Syrian civil war, distancing itself from the Syrian government. After a meeting with Hillary Clinton, the Chinese foreign minister declared that the government was willing to "support a period of political transition in Syria," although the country is still reluctant to support foreign intervention.
Algeria has been one of a small number of Arab and Islamic states, to oppose punitive measures against the Syrian government. It opposed (with Iran) Syria's suspension from the Organisation of Islamic Cooperation in 2012. It also opposed the Arab League decisions to encourage military support for the Syrian Opposition among member states, and opposed recognition of the National Coalition for Syrian Revolutionary and Opposition Forces, as the legitimate representative of the Syrian people, both decisions undertaken by the Arab League in 2013. Algeria was supported in its position by only two other Arab League states, Iraq and Lebanon. There is no concrete evidence that Algeria has been directly arming the Assad regime, but there are rumours of Algerian military aircraft regularly landing in Syria. The Algerian government is believed to be strongly opposed to regime change in Syria.
From 2011, Iraqi Government has sent Assad financial support. Iraq has opened its airspace for use by Iranian planes ferrying support to the Assad regime, and has granted trucks bound for Syria carrying supplies from the Iranian Revolutionary Guards passage through Iraqi territory. Iraqi government has signed a deal to provide Syria with diesel fuel.
The Houthis, have urged their supporters in Northern Yemen to support the Syrian government. It has been alleged by a defected Syrian air-force brigadier that the Houthis supplied 200 fighters to participate in the Siege of Maarat al-Numaan and the Jisr al-Shughur operation.
A Greece-based trading company, Naftomar, is reputedly the last firm arranging deliveries of liquefied petroleum gas (LPG), but, unlike the fuel sent from Venezuela and Russia, LPG is a peaceful material that plays a vital role in countries like Syria that have limited infrastructure for piping gas. International sanctions do not apply to LPG for humanitarian reasons.
The release of WikiLeaks's "Syria Files" beginning in July 2012 led to accusations that the subsidiary of an Italian arms company had provided communications equipment to the Syrian military in May 2011, and that, as late as February 2012, its engineers gave training on the use of the communications technology, including how it could be installed in helicopters. The company said the equipment was for civilian use and said it had not sold any technology to Syria since the beginning of the uprising.
According to the a report in the Daily Mail, a British newspaper, British companies sold sodium fluoride, a key ingredient in the manufacture of the deadly nerve gas sarin, to a Syrian firm from 2004-2010. Between July 2004 and May 2010, the British government issued five export licenses to two companies, with the last export license was issued in May 2010. The licenses are obtained prior to manufacture and the industry standard requires four to five months before the chemicals are delivered, thus allowing them to sell Syria sodium fluoride, necessary for the production of sarin. 
Spillover into Lebanon
The Syrian civil war has led to incidents of sectarian violence in northern Lebanon between supporters and opponents of the Syrian government, and armed clashes between Sunnis and Alawites in Tripoli. Fighting between rebels and government forces has spilled into Lebanon on several occasions. The Syrian Air Force has conducted air strikes on targets in Lebanon, while rebels have launched rockets on Hezbollah targets. Fighting between supporters of the Sunni sheikh Ahmed Al-Assir, who is against Hezbollah's involvement in Syria, and the Lebanese army has killed at least 15 of its soldiers.
At the beginning of summer 2012, two Hezbollah fighters were killed in a clash with Syrian rebels who were on Lebanese territory.
On 17 September, Syrian Ground-attack aircraft fired three missiles 500 metres (1,600 ft) over the border into Lebanese territory near Arsal. It was suggested that the jets were chasing rebels in the vicinity. The attack prompted Lebanese president Michel Sleiman to launch an investigation, whilst not publicly blaming Syria for the incident.
On 22 September, a group of armed members of the Free Syrian Army attacked a border post near Arsal. This was reported to be the second incursion within a week. The group were chased off into the hills by the Lebanese Army, who detained and later released some rebels due to pressure from dignified locals. Michel Sleiman praised the actions taken by the military as maintaining Lebanon's position being “neutral from the conflicts of others". He called on border residents to “stand beside their army and assist its members.” Syria has repeatedly called for an intensified crackdown on rebels that it claims are hiding in Lebanese border towns.
On 11 October 2012, four shells fired by the Syrian military hit Masharih al-Qaa, where previous shelling incidents have caused fatalities. Lebanon's position of ignoring the attacks and dissociating itself from the conflict remained unchanged.
In October 2012 Hassan Nasrallah denied Hezbollah members were fighting alongside the Syrian army, but that Lebanese in Syria were only protecting Lebanese inhabited villages from the Free Syrian Army.
Other violent incidents
Incidents at Syrian-Turkish border
During the 5 December 2011 night, about 35 armed fighters tried to cross the border of Syria from Turkey, but were engaged immediately by the Syrian border forces who inflicted several wounds to them and were able to repel them back to Turkey. Once they were back on Turkish soil, the Turkish army allegedly picked them up in trucks and took care of the injured fighters. A further attempt happened during the night of 12 December, when 15 infiltrators tried again to cross the border. They were unsuccessful and two of them were killed by Syrian border patrols.
F4 jet incident
On 22 June 2012, Syrian air defenses shot down a Turkish F-4 Phantom fighter jet, and both pilots were killed. The incident significantly raised tensions between the two countries. Syria stated that it had shot the fighter down using anti-aircraft artillery near the village of Om al-Tuyour, while it was flying over Syrian territorial waters one kilometer away from land. Turkey's foreign minister stated the jet was shot down in international airspace after accidentally entering Syrian airspace, while it was on a training flight to test Turkey's radar capabilities. Turkish Prime Minister Recep Tayyip Erdoğan vowed retaliation, saying: "The rules of engagement of the Turkish Armed Forces have changed ... Turkey will support Syrian people in every way until they get rid of the bloody dictator and his gang." Ankara acknowledged that the jet had flown over Syria for a short time, but they said such temporary overflights were common, had not led to an attack before, and alleged that Syrian helicopters had violated Turkish airspace five times without being attacked and that a second, search-and-rescue jet had been fired at. Assad later expressed regret over the incident. In August 2012, reports appeared in some Turkish newspapers claiming that the Turkish General Staff had deliberately misinformed the Turkish government about the fighter's location when it was shot down. The reports said that a NATO command post at Izmir and a British base in Cyprus had confirmed that the fighter was shot down inside Syrian waters and that radar intelligence from U.S. forces had disproved any "accidentally entered Syrian waters" flightpath error. The General Staff denied the claims.
October 2012 cross-border clahses
Tensions were further raised later that year when Syrian mortar rounds began landing in Turkish territory. On 3 October, a Syrian mortar shell hit the Turkish town of Akçakale, killing 5 civilians. Turkey responded by shelling Syrian army positions along the border. Throughout October, Syrian mortar shells repeatedly landed in Turkish territory, and the Turkish military launched retaliatory artillery and mortar strikes, firing into Syria a total of 87 times. These attacks reportedly killed 12 Syrian soldiers and destroyed several tanks.
February 2013 bombing
Earlier, on 11 February 2013, the border near Reyhanlı was the scene of a deadly attack, when an explosion killed 17 people and injured 30 more.
May 2013 border bombing
On 11 May 2013, two car bombs exploded in the town of Reyhanlı, Hatay Province, Turkey. At least 51 people were killed and 140 injured in the attack. The attack was the deadliest single act of terrorism to occur on Turkish soil.
In response to the attacks, the Turkish government sent large numbers of air and ground forces to increase the already heavy military presence in the area.
By 12 May 2013, nine Turkish citizens, alleged to have links to the Syrian intelligence agency, had been detained. On 21 May 2013, the Turkish authorities charged the prime suspect, the state-run Anatolia news agency reported. Four other suspects were also charged. 12 people had been charged in total. All suspects were Turkish nationals that Ankara believes were backed by the Syrian regime.
On 30 September 2013, some websites claimed that the Islamic State of Iraq and the Levant (ISIL), the al-Qaeda group operating in Iraq and Syria, accepted responsibility for the attack, threatening further attacks against Turkey.
2013 helicopter incident
On September 2013, Turkish jets shot down a Syrian helicopter on the Syrian-Turkish border. According to Turkish official statement, Turkish warplanes made the intercept after Syrian Mi-17 helicopter had crossed into Turkish airspace and the government warned it had taken all necessary measures to defend itself against any further such violations. Syrian army acknowledged the helicopter had strayed into Turkish airspace for a short time, while monitoring "terrorists" moving across the border into Syria, but said it was an accident and that the aircraft was on its way back when it was shot down. In a statement carried by Syrian state news agency SANA, it accused Prime Minister Tayyip Erdogan's government of trying to increase tensions between the two countries.
Tensions at Syrian-Israeli border
In late 2012, border tensions between Israel and Syria escalated. On 25 September 2012, several mortar shells landed in the Israeli-occupied Golan Heights, landing in an open area adjacent to the border fence. Overall, throughout October and early November, several Syrian mortar and light artillery shells hit the Golan Heights. One mortar round may have been responsible for a brushfire that erupted in the area. On 3 November, three Syrian tanks entered the demilitarized zone in the central Golan Heights as a number of mortar shells were fired into the area. On 5 November, an Israeli army jeep was damaged by Syrian army gunfire as it patrolled the border. On 11 November, after a Syrian 120mm mortar round hit the eastern Golan Heights, the Israeli army responded by firing an electro-optic anti-tank missile in the direction of a Syrian mortar crew, but they deliberately missed them, intending it as a warning shot. On 12 November, another Syrian mortar shell struck the Golan Heights, and Israeli tanks deployed along the border responded by targeting two Syrian mortar launchers. A direct hit was confirmed. A shell fired from Syria, where insurgents and government troops are locked in fierce fighting, exploded in the Israeli-occupied part of the Golan Heights plateau on Sunday, 14 July 2013.
Alleged Israeli airstrikes
On 30 January 2013, about ten jets bombed a convoy believed to be carrying Russian-made SA-17 anti-aircraft missiles to Lebanon. The attack, attributed by some media reports to Israeli airforce, did not result in any counterattacks from Syria, although Syria has said it reserves the right to retaliate. Western intelligence sources reported that Iranian general Hassan Shateri had been killed in the airstrike. Iran acknowledged his death at the hands of the Israelis without further details. Israel refused to comment on its involvement in the incident.
News organizations reported that Israel attacked Syria on the night between 2 and 3 May 2013. US officials said that the Israeli war planes shot into Syria from Lebanese air space, and that the warplanes did not enter Syrian air space. No counter-attacks by Syria were reported at any front, and the Syrian ambassador to the UN said that he was not aware of any attacks on Syria by Israel. Israel as well declined any comment. Another alleged attack was reported to be a set of massive explosions in Damascus on the night of 4–5 May 2013. Syrian state media described this as an "Israeli rocket attack", with the targets including a military research center of the Syrian government in Jamraya. The Daily Telegraph reported anonymous Israeli sources as saying that this was an Israeli attack on Iranian-made guided missiles allegedly intended to be shipped to Hezbollah. The Syrian Observatory for Human Rights, an opposition monitoring group based in Britain, said at least 42 Syrian soldiers were killed in the strikes.
Another violent event, possibly linking Israel, occurred in July 2013 in Latakia. Both Syria and Israel denied any report, while Hezbollah claimed that large explosions in Latakia area were caused by rebel mortar fire. Reportedly, the attack targeted Russian-made Yakhont anti-ship missiles near the city of Latakia, and killed several Syrian troops. Russian news agency also reported of Turkish involvement in the incident, though Turkey immediately denied.
Iraqi-Syrian border incidents
The Akashat ambush was a well planned assault against a Syrian Army convoy defended by Iraqi soldiers that took place on 4 March 2013, as the group was travelling in the province of Anbar, next to the border with Syria. The Islamic State of Iraq claimed responsibility for the ambush on March 11. 51 Syrian soldiers killed in the clashes.
Another 9 Iraqi soldiers were killed as well from insurgent fire. The attackers carried unknown casualties.
A number of clashes and incidents took place on Jordanian Syrian border since the beginning of civil war, mostly involving Jordanian Army and Syrian Army, but occasionally also the Syrian rebels.
On 22 October 2012, a Jordanian soldier died in a gunfight between Jordanian troops and Islamic militants attempting to cross the border into Syria. Sameeh Maaytah, the Information Minister of Jordan, said the soldier was the first member of the Jordanian military to be killed in clashes connected to the civil war in Syria.
In February 2012, German Foreign Minister Guido Westerwelle warned that a proxy war in Syria could "cause a confrontation that drags in even Moscow and Beijing". Before his departure to the 2012 G8 Summit the Russian Prime Minister Dmitry Medvedev warned, that "actions, which undermine state sovereignty" may well end in "a full-blown regional war" and even the "use of nuclear weapons". Syrian state institutions, according to another Brookings scholar,[who?] citing post-invasion Iraq, cautioned against the goal of an immediate purge of all Ba'athists.
In July 2012, Switzerland ceased arms exports to the UAE after it emerged Swiss weapons were finding their way to opposition fighters. The Swiss decision came shortly after the UN human rights chief, Navi Pillay, called for an urgent stop to arms transfers to government and opposition forces so as to avoid "further militarisation" of the conflict. The director of the Saban Center for Middle East Policy had previously argued that, while "uncontrolled militarization will turn the Syrian uprising into a wider conflict that could draw in jihadis and other extremists from across the Muslim World", militarisation was inevitable, and so the US should help facilitate and guide it. Marc Lynch argued the opposite in February 2012, as the provision of weapons from Saudi Arabia and Qatar was being mooted: "It is unlikely that arms from the outside would come close to evening the balance of power, and would only invite escalations from Syrian regime forces".
August 2012, Israeli minister Ayoob Kara said that he was facilitating aid to Syrian refugees while also in contact with several Syrian government officials who were considering defecting from the regime. Kara stated that he was in contact with some Syrian opposition partisans who asked for his help, citing his international ties as a potential influence in increasing pressure on Assad. Kara added that the Israeli government rejected his request to interfere.
