OPCW inspectors were hastily dispatched to Syria this month and have visited most of the 23 sites Damascus declared and begun overseeing destruction work to ensure that machines used to mix chemicals and fill munitions with poison gas are no longer functioning.
Syria is believed to possess around 1,000 metric tons of chemical weapons, including mustard gas and sarin.
It has not yet been decided how or where destruction of Syria's chemical weapons will happen. Syria's declaration includes a general plan for destruction that will be considered by the OPCW's 41-nation executive council on Nov. 15.
Norway's foreign minister announced Friday that the country had turned down a U.S. request to receive the bulk of Syria's chemical weapons for destruction because it doesn't have the capabilities to complete the task by the deadlines given.
