The Pentagon on Monday confirmed it has set up a small Marine base in northern Iraq to protect a nearby Iraqi military base, in the wake of a weekend attack that left one Marine dead and several others injured. The new outpost was attacked again Monday, but no Marines were hurt, the Pentagon said. The Marines returned fire, killing at least two ISIS militants, according to Col. Steve Warren, a U.S. military spokesman in Iraq. Col. Warren also insisted the Marines are there to provide “force protection” and not to serve as combat forces. An estimated 100 to 200 Marines from the 26th Marine Expeditionary Unit are stationed at the outpost.
