The Executive Council of the Organization for the Prohibition of Chemical Weapons (OPCW) has convened on Monday at its headquarters in Hague, Netherlands to discuss the recent alleged chemical attack in Syria.

The suspected attack was said to have occurred in the rebel-held town of Douma in Eastern Ghouta on April 7.

The chemical weapons watchdog said its fact-finding mission arrived at the attack site on Saturday to verify whether there was a chemical attack on April 7, but not to identify "the responsible side".

But the United States and its allies, the United Kingdom and France insisted that the Syrian governmental forces undoubtedly launched a chemical weapons attack, based on which they struck some targets in Syria only several hours before the mission's arrival to Syria.

The OPCW's closed-door meeting may last for the entire day.
