Washington, SANA- The United States announced on Wednesday that ISIS terrorist organization is believed to be responsible for sulfur mustard gas attacks in Syria and Iraq last year.
State Department spokesman Mark Toner pointed out in statements that ISIS terrorists were responsible for a mustard gas attack in the town of Mareh, in the northern countryside of Aleppo on Aug. 21 “largely based on photographic evidence as well as Syrian opposition description of the event.”
Toner added, based on available information, the United States believed that ISIS was responsible for mustard gas attacks in Iraq.
Sulfur mustard is a Class 1 chemical agent, which means it has very few uses outside chemical warfare. Used with lethal effectiveness in World War One, it causes severe delayed burns to the eyes, skin and respiratory tract.
