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 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.That Sarin was used in Khan al-Asal was also the conclusion of the Russian investigation of the attack.
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.
The victims’ symptoms described by medics – were consistent with exposure to a nerve agent, including shortness of breath, disorientation, runny nose, eye irritation, blurred vision, nausea, vomiting, general weakness, and eventual loss of consciousness.
