The world's chemical watchdog on Saturday adopted a plan to dismantle Syria's chemical arsenal, shortly before the UN Security Council votes on a resolution including the blueprint.

"The decision is adopted and it is effective immediately," Organization for the Prohibition of Chemical Weapons spokesman Michael Luhan told journalists after the Executive Council meeting.

US Secretary of State John Kerry has called the OPCW document the "rules and regulations" of Syria's chemical disarmament to be enshrined in the UN resolution that is to be voted on at 0000 GMT Saturday.

The draft OPCW document says the watchdog will start chemical weapons inspections no later than October 1.

The 41-member OPCW Executive Council usually takes decisions by consensus, or they require a two-thirds majority vote to pass.

In case of non-compliance with the plan, which requires all Syrian chemical weapons and facilities destroyed by mid-2014, the OPCW will discuss the allegation and then take it to the UN Security Council and General Assembly.
