JAYVEE: Islamic State launches chemical attack against U.S., Iraqi forces, Pentagon confirms.

Chairman of the Joint Chiefs of Staff Gen. Joseph Dunford told members of the Senate Armed Services Committee “mustard blister agent” was released in the vicinity of a military airfield in the western part of al Qayyara, about 40 miles south of Mosul, in northern Iraq.

The airbase has been designated by Iraqi and American commanders as the main logistics hub to support a series of firebases that will serve as jumping-off points for 14 Iraqi Army brigades and thousands of peshmerga and militia fightersfor the eventual siege of Mosul.

If ISIS had been dealt with seriously three years ago, they wouldn’t be holding dress rehearsals with chemical weapons today.
