Syria Cease-Fire Goes Into Effect Sunday

The Syria cease-fire that the United States and Russia have agreed upon goes into effect Sunday at noon Damascus time.

That's according to U.S. officials and the Jordanian government, which is also involved in the deal. The U.S. officials weren't authorized to speak publicly on the matter and demanded anonymity.

The former Cold War foes have been backing opposing sides in Syria's war. Moscow has staunchly backed Syrian President Bashar Assad, supporting Syrian forces militarily since 2015. Washington has backed rebels fighting Assad.

Secretary of State Rex Tillerson says the cease-fire in southwest Syria is designed to reduce violence in an area near Jordan's border that is critical to that U.S. ally's security.
