The U.S. military launched strikes against Iran Tuesday evening in direct retaliation for the downing of an American Apache helicopter on Monday.

U.S. Central Command announced the action on X:

“U.S. Central Command (CENTCOM) forces began launching self-defense strikes against Iran at 5 p.m. ET today at the Commander in Chief’s direction, in response to yesterday’s downing of a U.S. Army Apache helicopter,” CENTCOM said in the post.

CENTCOM called the mission “a proportional response to unjustified Iranian aggression.”
