 In this Aug. 21, 2013, file citizen journalism image provided by the Local Committee of Arbeen which has been authenticated based on its contents and other AP reporting, a Syrian girl receives treatment at a makeshift hospital in Arbeen town, Damascus, Syria. The early-morning barrage against rebel-held areas around the the Syrian capital Damascus immediately seemed different: The rockets made a strange, whistling noise. Seconds after one hit near his home, Qusai Zakarya says he couldn’t breathe, and he desperately punched himself in the chest to get air. Hundreds of suffocating, twitching victims flooded into hospitals. Others were later found dead in their homes, towels still on their faces from their last moments trying to protect themselves from gas. Doctors and survivors recount scenes of horror from the alleged chemical attack a week ago. (AP Photo/Local Committee of Arbeen, File) less
