US launches strike on Iran-backed forces in Iraq, first since February

The U.S. launched a Tuesday strike on Iranian-backed forces in Iraq in the first attack in the country since massive strikes in February.

U.S. fighter jets struck several Iranian-aligned militia groups in the Babil province south of Baghdad, according to Iraqi officials, killing several fighters.

Yehia Rasool, a spokesperson for Iraq's armed forces commander, said it was a "serious and uncalculated transgression" on his country and the attack could undermine the ability to combat ISIS.
