WASHINGTON (AP) _ The American service member killed this week by a roadside bomb in northern Syria was a 36-year-old Army soldier from Texas.

The Defense Department identified him Saturday as Master Sgt. Johnathan J. Dunbar of Austin. 

He died Friday as a result of injuries suffered when an improvised explosive device detonated near his patrol in Syria, not far from the border with Turkey. 

A Briton also was killed and five other people were wounded in Thursday's bombing. 

Dunbar was assigned to the headquarters of the U.S. Army Special Operations Command in Fort Bragg, North Carolina.

He is the fourth American service member to die in Syria since the U.S. began attacking Islamic State group militants there in September 2014.
