US assesses reported Syrian chemical use

The US Defence Secretary has said that his country and its allies are still trying to figure out details of Syria's suspected use of chemical weapons against its own people.

"We are continuing to assess what happened - when, where," said Chuck Hagel on Monday.

"I think we should wait to get the facts before we make any judgments on what action, if any, should be taken, and what kind of action."
