*Syria sent a letter to the United Nations Secretary General which said that Assad signed a legislative decree providing the accession of Syria to the Chemical Weapons Convention. In the letter, Assad said Syria would observe its CWC obligations immediately, as opposed to 30 days from the date of accession, as stipulated in the treaty.
