Chemical weapons inspectors have verified 11 sites in Syria that were identified by Damascus on Wednesday, continuing their process of eliminating Syria’s arsenal.

“The OPCW mission has now conducted verification activities at a total of 11 sites that are identified by Syria's disclosure,” the Hague-based Organization for the Prohibition of Chemical Weapons said, according to Agence France-Presse (AFP).

The Nobel Peace Prize-winning OPCW, along with the U.N., have had a team of 60 experts and support staff in Syria since the beginning of October, to carry out the terms of a U.N. Security Council resolution of destroying Syria’s chemical weapons.

The resolution was adopted following a U.S.-Russian deal that came in the wake of an August 21 sarin attack on the outskirts of Damascus.

The United States threatened military action against the Syrian regime in response to the attack, despite the government’s denial of responsibility.
