ISIS fires chemical agent at U.S., Iraqi troops

The Islamic State fired a shell with a mustard agent at U.S. and Iraqi troops stationed at the Qayyarah air base in Iraq on Tuesday afternoon, the Pentagon has confirmed.

“It was rocket that was fired, and it has an “oily tar-like substance” on one of the fragment,” a military official at U.S. Central Command told the Washington Examiner. “An initial filed test was POSITIVE for Mustard agent, but a second more sophisticated test was NEGATIVE. So the fragment is undergoing further testing, but the level of concern is not as high as when the first reports came in.”
