AMSTERDAM (Reuters) - The head of the global chemical weapons watchdog overseeing the destruction of Syria's toxic stockpile is considering launching a fact-finding mission on his own initiative to investigate reports of chlorine gas attacks there, sources said.

Syria became a member of the Organisation for the Prohibition of Chemical Weapons (OPCW) last year as part of a deal with Russia and the United States to destroy its chemical weapons programme.
