A day earlier, the body that polices the global treaty outlawing chemical weapons said it had received a preliminary submission from Syria.
No details have been released of what is in the Syrian declarations, and OPCW spokesman Michael Luhan refused to give any more information about the latest submission.
Under a U.S.-Russia agreement aimed at swiftly ridding Syria of its chemical arsenal, Damascus had until Saturday to submit a full list to the organization of its chemical weapons and production facilities so they can be secured and destroyed.
U.S. officials said last week that Washington and Moscow agreed that Syria had roughly 1,000 metric tons (1,100 tons) of chemical weapons agents and precursors, including blister agents, such as sulfur and mustard gas and nerve agents like sarin.
In the aftermath of the U.N. report that concluded sarin had been used in an Aug. 21 attack in Damascus, the Hague-based chemical weapons watchdog is looking for ways to fast-track moves to secure and destroy Syria's arsenal of poison gas and nerve agents as well as its production facilities.
