American service members killed while conducting routine patrol in Syria

The U.S. military says American service members have been killed during an explosion while conducting a routine patrol in Syria.

The military said in a tweet about Wednesday's blast in the northern Syrian town of Manbij: "We are still gathering information and will share additional details at a later time."

A Syrian war monitor reported earlier that at least two U.S. soldiers were killed in the suicide attack outside a restaurant in Manbij.
