The Organisation for the Prohibition of Chemical Weapons (OPCW) announced April 29 that it would begin a fact-finding mission into allegations of the use of chlorine gas in Syria. Although both rebel forces and the Syrian government acknowledge that the chemical weapon was used on the Syrian town of Kafr Zita, both factions deny responsibility for the attack. Chlorine was not a chemical Syria was required to give up, but the use of chlorine gas is prohibited under the Chemical Weapons Convention, to which Syria is a signatory. Some western governments believe that Syria has failed to declare all the chemical weapons in its possession, including chlorine gas, and has retained some of its chemical stockpile.
