WASHINGTON (Reuters) - The U.S. ambassador to Syria said on Wednesday there is no evidence so far to back reports that chemical weapons were used in Syria on Tuesday, but the United States has a large team investigating the issue.
"So far, we have no evidence to substantiate the reports that chemical weapons were used yesterday. But I want to underline that we are looking very carefully at these reports," Robert Ford, who was recalled from Damascus in February 2012, told a hearing of the House of Representatives Foreign Affairs Committee.
