The Organization for the Prevention of Chemical Weapons said it had received "the expected" accounting, the BBC reported.
Syria is believed to have about 1,120 tons of the internationally banned toxins.
A spokesman for OPCW, based in The Hague, Netherlands, said some documentation had been received "and there is more come," The Guardian reported.
The information is being reviewed by the organization's technical body and the documents have not yet been shared with other parties involved in the negotiations with Syria, said a spokesman for the British foreign ministry. Consequently, a scheduled meeting of the U.N. Security Council to formulate a plan for Syria to lay down its arms will be delayed.
The party to which Syrian deputy Prime Minister Qadri Jamil is a member sought Friday to retract his comments that Syria was seeking a cease-fire. Party officials claimed Jamil spoke in his capacity as a party member, not as a member of the government.
Jamil made his comments in an interview conducted in a government building and arranged by a government information officer.
