グータ化学攻撃
According to Human Rights Watch, hundreds of kilograms of sarin were used in the attack, which it said suggested government responsibility, as opposition forces were not known to possess significant amounts of sarin.
The Russian government dismissed the initial UN report after it was released, calling it "one-sided" and "distorted." On 17 September, Russian Foreign Minister Sergei Lavrov reiterated his government's belief that the opposition carried out the attacks as a "provocation." The United Nations High Representative for Disarmament Affairs Angela Kane said the inspection team would review Russia's objections.
Within a month of the attacks, Syria agreed to join the Chemical Weapons Convention and allow all its stockpiles to be destroyed. The destruction began under OPCW supervision on 6 October 2013. On 23 June 2014, the last shipment of Syria's declared chemical weapons was shipped out of the country for destruction. By 18 August 2014, all toxic chemicals were destroyed aboard the US naval vessel MV Cape Ray.
Nine months after the attack, there is evidence that mothers from the affected areas are giving birth to children with defects and as stillborn.
二回目の攻撃は8月21日午前5:00に西グータで行われた。モダミヤ情報局に務めていた目撃者によると、彼は8月21日の早朝にモダミヤの2つの地区に7つのロケットが落ちたのを目撃したと述べている。彼の証言によると4つのロケットがラウダモスクの隣に落ち、3つがカウエ通りとゼイトウネ通りの間に落ちた。また、ロケットは全て同じタイプだった。彼が居た場所はラウダモスクから500メートルほど離れている。西グータの攻撃では化学弾頭は見つからなかったが、ロケットのうちの一つは122 mm GRAD 無誘導地対地ロケットと同じ型のエンジンであり、このロケットは破片榴弾、白リン弾、サリンを含む化学弾頭を搭載することができる。西グータで取得された13の環境サンプルからは、サリンは検出されなかった。しかし、その3つからはその"分解物もしくは副生成物"が検出された。
Murad Abu Bilal, Khaled Naddaf and other Center for Documentation of Violations in Syria and Local Coordination Committees of Syria (LCC) media staff went to Zamalka soon after the attacks to film and obtain other documentary evidence. Almost all the journalists died from inhalation of the neurotoxins, except Murad Abu Bilal, who was the only Zamalka LCC media member to survive. The videos were published on YouTube, attracting world-wide media attention.
Experts who have analysed the first video said it shows the strongest evidence yet consistent with the use of a lethal toxic agent.
