The Organisation for the Prohibition of Chemical Weapons [5] (OPCW) announced April 29 that it would begin a fact-finding mission into allegations of the use of chlorine gas [6] in Syria. Although both rebel forces and the Syrian government acknowledge that the chemical weapon was used [7] 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 [8], to which Syria is a signatory [9]. 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 [10].
