Syria has completed the handover of an inventory of its chemical arsenal by the deadline set as part of a deal to head off military strikes, the world's chemical weapons watchdog said.
The "OPCW has confirmed that it has received the expected disclosure from the Syrian government regarding its chemical weapons program," the Hague-based Organisation for the Prohibition of Chemical Weapons said in an email received by AFP.
"The Technical Secretariat is currently reviewing the information received," it added.
The OPCW has postponed a meeting of its Executive Council set for Sunday, which had been due to discuss how to dismantle Syria's chemical weapons program.
The US-Russian disarmament agreement, worked out as Washington threatened military action in response to an August 21 chemical weapons attack outside Damascus, requires Syria to hand over the whole of its arsenal which is to be destroyed by mid-2014.
UN diplomats are trying to thrash out a resolution to ensure Syrian compliance with the deal, but they first need the document laying out what US Secretary of State John Kerry called the "rules and regulations" of the disarmament to be agreed by the OPCW.
Following the deal, Syria asked to join the Chemical Weapons Convention, which the OPCW enforces. OPCW experts will now analyse the inventory handed over by Damascus to draw up a realistic timetable for destroying the chemicals, delivery systems and production facilities.
According to the framework agreed by Washington and Moscow, OPCW weapons inspectors are to complete inspections of Syrian weapons sites and destruction of production and mixing/filling equipment by November.
But the international consensus on the plan has not carried over into negotiations on the wording of a UN Security Council resolution to back it up.
The Council's five permanent members - Britain, China, France, Russia and the United States - have been wrangling over the text of the resolution since Monday in a bid to find common ground.
The United States, France and Britain want a strongly-worded resolution, possibly under the UN Charter's Chapter VII, which could allow the use of force or sanctions to ensure compliance.
But Russia, a key ally of Damascus, opposes all references to use of force.
