ISIS Used Mustard Gas Against Kurdish Forces in Iraq, U.S. Believes

U.S. officials believe the terror group ISIS used chemical weapons in Iraq this week, defense and intelligence officials said Thursday.

The terror group used mustard gas in an attack against Kurdish fighters, two defense officials and an intelligence official told NBC News. Mustard gas, infamously used during World War I, can cause blisters, blindness and respiratory damage.

The defense officials said this is the second time ISIS has used chemical weapons — the first occurred in "recent weeks" in Syria — but they declined to provide more details, citing operational security concerns.
