Some of the victims of the Ghouta attack 21 August 2013

Use of chemical weapons in the Syrian Civil War has been confirmed by the United Nations. The deadliest attacks were the Ghouta attack in the suburbs of Damascus in August 2013 and the Khan al-Asal attack in the suburbs of Aleppo in March 2013. Several other attacks have been alleged, reported and/or investigated.

A U.N. fact-finding mission and a UNHRC Commission of Inquiry have simultaneously investigated the attacks. The U.N. mission found likely use of the nerve agent Sarin in the case of Khan Al-Asal (19 March 2013), Saraqib (29 April 2013), Ghouta (21 August 2013), Jobar (24 August 2013) and Ashrafiyat Sahnaya (25 August 2013). The UNHRC commission later confirmed the use of Sarin in the Khan al-Asal, Saraqib and Ghouta attacks, but did not mention the Jobar and the Ashrafiyat Sahnaya attacks.

The UNHRC commission also found that the Sarin used in the Khan al-Asal attack bore "the same unique hallmarks" as the Sarin used in the Ghouta attack and indicated that the perpetrators likely had access to chemicals from the Syrian Army's stockpile.

Background[edit]

The use of chemical weapons must be seen in the context of the Syrian Civil War. On 20 August 2012, President Barack Obama used the phrase "red line"[1] in reference to the use of chemical weapons. On 6 September 2013 a bill was filed to authorize the use of military force against the Syrian military, mainly in response to the use of sarin in the Ghouta attack on 21 August 2013.[2] On 9 September 2013, the U.S. Secretary of State John Kerry stated that the air strikes could be averted if Syria turned over "every single bit" of its chemical weapons stockpiles.[3] Hours after Kerry's statement, the Russian foreign minister Sergey Lavrov announced that Russia had suggested to Syria that it relinquish its chemical weapons.[4] The Syrian foreign minister Walid al-Moallem immediately welcomed the proposal.[4][5]

Prior to September 2013 the Syrian government had not publicly admitted to possess chemical weapons, although Western intelligence services believed it to hold one of the world's largest stockpiles.[6]

Incidents[edit]

The map marks the position of reported chemical weapons attacks in the Syrian Civil War. Yellow markers indicate chlorine attacks. Red indicate a more deadly chemical weapon agent.

The table below lists the reported attacks and the main points. See the main articles for details.[N 1]

Other related incidents[edit]

In December 2012, the chemical plant SYSACCO 29 kilometers (18 mi) east of Aleppo was taken by rebel fighters from the Al-Nusra Front. The factory produces chlorine among other chemicals.[7] On 5 November 2014, the Syrian UN-ambassador Bashar al-Jaafari, said "terrorist organizations stole about 200 tons of [chlorine gas] from" the factory.[8]

On 30 May 2013, Turkish newspapers reported that Turkish security forces had arrested Al-Nusra Front fighters in the southern provinces of Mersin and Adana near the Syrian border and confiscated 2 kg of sarin gas.[9] The Turkish Ambassador to Moscow later said that tests showed the chemical seized was not sarin, but anti-freeze (anti-freeze is either Methanol or Isopropyl alcohol).[10] In September six of those arrested in May were charged with attempting to acquire chemicals which could be used to produce sarin; the indictment said that it was "possible to produce sarin gas by combining the materials in proper conditions."[11]

According to Syria, on 1 June 2013, the Syrian Army seized two cylinders holding the nerve agent sarin in an area controlled by opposition fighters. The Syrian government declared the two cylinders "as abandoned chemical weapons" and told the OPCW that "the items did not belong to" them.[12] On 14 June 2014, the Joint OPCW-UN Mission confirmed that the cylinders contained sarin.[12] On 7 July 2014, the U.N. Secretary-General Ban Ki-Moon informed the U.N. Security Council about the findings.[12]

Investigations[edit]

The UN mission to investigate alleged use of chemical weapons[edit]

The United Nations Mission to Investigate Allegations of the Use of Chemical Weapons in the Syrian Arab Republic was a fact-finding mission to investigate possible use of chemical weapons in Syria. On 16 September 2013 the mission published a report with focus on the Ghouta attacks.[19] On 12 December 2013, the UN mission delivered its final report.[13]

The UNHRC commission of inquiry[edit]

The Independent International Commission of Inquiry on the Syrian Arab Republic was set up by the United Nations Human Rights Council (UNHRC) on 22 March 2011 to investigate human rights violations during the Syrian civil war. In its report dated 12 February 2014 they confirmed the use of Sarin in the case of Khan Al-Assal (19 March 2013), Saraqib (29 April 2013) and Al-Ghouta (21 August 2013). The UNHRC commission also found that the Sarin used in the Khan al-Asal attack bore "the same unique hallmarks" as the Sarin used in the Ghouta attack and indicated that the perpetrators likely had access to chemicals from the Syrian Army's stockpile.[18]

In its report dated 13 August 2014 they accused Government forces of using chlorine gas in 8 incidents in Idlib and Hama governorates in April 2014.[21]

The Russian Khan al-Asal investigation[edit]

Vitaly Churkin, russia's ambassador to the UN, said that its Syrian ally had asked Russian experts to look into the Khan al-Assal attack. A Russian team investigated the Khan al-Asal incident on 19 March 2013.[13] The Russian UN ambassador Vitaly Churkin delivered a report with analysis of the samples taken at the site to the UN Secretary General Ban Ki-moon on 9 July 2013.[13] Churkin said the chemical agent was carried by a "Bashair-3 unguided projectile", which was produced by the Bashair al-Nasr Brigade, a rebel group affiliated with the Free Syrian Army.[48]

The OPCW Fact-Finding Mission in Syria[edit]

On 29 April 2014, the Director General Ahmet Üzümcü of the Organisation for the Prohibition of Chemical Weapons (OPCW) announced the creation of an OPCW mission to establish the facts surrounding allegations of the use of chlorine gas for hostile purposes in Syria.[49] The Syrian Government has agreed to the mission.[50]

On 27 May 2014, members of the mission were ambushed and briefly held by gunmen in rebel-held territory as it headed toward Kafr Zita to investigate the alleged chlorine gas attacks.[51] The opposition Hama Media Centre said the attack on the convoy was carried out by President Bashar Assad's forces.[52]

In its third report dated 18 December 2014, the mission concluded that chlorine was used in the villages of Talmenes, Al-Tamanah and Kafr Zita, but did not assign blame.[20]

Other allegations[edit]

In February 2012, a defected lieutenant who worked in the chemical weapons department claimed that "BZ-CS, Chlorine Benzilate, which damages people’s nerves and makes them fade away, is being used in Bab Amr." He said that some Syrian soldiers had been supplied with gas masks for protection.[53]

In 2015 the OPCW-UN Joint Mission in Syria disclosed previously undeclared traces of sarin and VX precursor compounds in a military research site where use of those compounds had not been previously declared.[54][55]
