President Barack Obama has decided to return a U.S. ambassador to Syria after a four-year hiatus as talks between the two nations intensify, U.S. media reported on Tuesday. The State Department informed Syria's ambassador to Washington, Imad Mustafa, of Obama's intention on Tuesday night, a senior administration official told the Washington Post. By returning a senior U.S. envoy to Damascus, Obama is seeking to carve out a far larger role for the United States in the region as he works to rehabilitate U.S. relations with the Islamic world and the Arab Middle East, the newspaper said. "It's in our interests to have an ambassador in Syria," a senior administration official told CNN. Mustafa welcomed the decision to name a U.S. envoy to increase dialogue among stakeholders in the Middle East, CNN said. The announcement of a new ambassador is expected to be made later this week but no individual has been chosen to fill the post, Reuters quoted the report as saying.
