US warns ISIS could get ahold of Syria's chemical weapons

The United States is concerned that the Islamic State group and other terrorists could get a hold of chemical weapons if Syria is hiding any stockpiles, the U.S. ambassador to the United Nations said Thursday.

Samantha Power spoke to reporters after the Security Council received a briefing from Sigrid Kaag, who heads the international effort to rid Syria of its chemical weapons.

The joint mission of the United Nations and the Organization for the prohibition of Chemical Weapons will end at the end of the month after destroying nearly all of Syria's declared stockpile. But Kaag said the OPCW is still working with Syria to resolve discrepancies in its declaration, which she said range from outdated records to discrepancies on the volume of materials.

Power said the U.S. is concerned not only that President Bashar Assad's regime still has chemical weapons but that any stockpiles left behind could end up in the hands of the Islamic State group, which has seized large swaths of Syria and Iraq.
