WASHINGTON–The United States is still unsure who directed an unprovoked attack on Feb. 7 on U.S. and U.S.-backed rebel forces at the Syrian Democratic Forces headquarters in Syria, Defense Secretary Jim Mattis said on Saturday. He acknowledged accounts that Russian civilian contractors were involved.

Reuters has reported that about 300 men working for a Kremlin-linked Russian private military firm were either killed or injured in Syria.
