A commander from Kataib Hezbollah, an Iran-backed armed group in Iraq that the Pentagon has blamed for attacking its troops, was killed in a U.S. strike on Wednesday, the U.S. military said.

"(U.S.) forces conducted a unilateral strike in Iraq in response to the attacks on U.S. service members, killing a Kataib Hezbollah commander responsible for directly planning and participating in attacks on U.S. forces in the region," a statement from the military said.
