The first four chemical weapons experts from the OPCW have arrived in Syria on a fact-finding mission (FFM) into the April 7 Douma incident, while Western leaders continue to blame the government for the alleged attack. “We will facilitate the arrival of the team to anywhere they want, in Douma, to check whether or not there was use of chemical substances,” said Bashar Jaafari, Syria’s envoy to the UN in New York, adding that a second team is due to arrive on Friday.
