Feb. 4 (UPI) -- "Battle-hardened" Islamic State militants could retake key territory in Syria after U.S. troops leave the war-torn country, a report from the Department of Defense's inspector general said Monday.
The watchdog warned the withdrawal could lift counterterrorism pressure off the militant group -- also identified as ISIS, ISIL and Daesh -- and lead to a resurgence. The inspector general based its report on information provided by the Department of Defense.
