U.N. cites concerns over possible gaps in Syria's declared chemical arms

UNITED NATIONS (Reuters) - The United Nations said on Thursday that discrepancies and questions still surround Syria's chemical weapons declaration as the United States expressed concern that any omitted toxins could fall into the hands of the Islamic State extremist militants.

Sigrid Kaag, head of a joint U.N. and Organisation for the Prohibition of Chemical Weapons (OPCW) mission overseeing the destruction of Syria's chemical weapons, said that since President Bashar al-Assad's government submitted its original declaration late last year, Damascus had made four amendments.
