FILE - This Aug. 21, 2013, citizen journalism image provided by the Media Office Of Douma City which has been authenticated based on its contents and other AP reporting, shows a Syrian man mourning over a dead body after an alleged poisonous gas attack fired by regime forces, according to activists, in Douma town, Damascus, Syria. The U.S. government insists it has the intelligence to prove a connection between the government of President Bashar Assad to the alleged chemical weapons attack last month that killed hundreds of people in Syria_but in the absence of such evidence, Damascus and its ally Russia have aggressively pushed another scenario: that rebels carried out the Aug. 21 chemical attack.
