The Pentagon said a lone gunman with the Islamic State, or ISIS, carried out the shooting ambush near the ancient desert city of Palmyra.

The gunman killed the two soldiers, as well as a U.S.

civilian interpreter, and also wounded three U.S.

troops.

The Americans were on a joint mission with Syrian forces and the Syrians killed the ISIS gunmen, the Pentagon said.

U.S.

U.S.

forces have remained in Syria to guard against a resurgence of ISIS.
