(Reuters) Global chemical weapons investigators have gone to Turkey to collect samples as part of an inquiry into an alleged chemical weapons attack in neighbouring Syria last week that killed 87 people.
The fact-finding mission was sent by the Organisation for the Prohibition of Chemical Weapons (OPCW) in The Hague to gather bio-metric samples and interview survivors, sources told Reuters on Thursday.
The toxic gas attack on April 4, which killed scores of people including children, prompted a U.S. cruise missile strike on a Syrian air base and widened a rift between the United States and Russia, a close ally of Syrian President Bashar al-Assad in his conflict with rebels and militants fighting to oust him.
Syrian authorities have repeatedly denied using any chemical weapons. Russian officials said the gas had been released by an air strike on a poison gas storage depot controlled by rebels. Washington said that account was not credible, and rebels have denied it.
