Iran state TV says Tehran has launched “tens” of surface-to-surface missiles at Iraq’s Ain Assad air base housing U.S. troops over America’s killing of a top Iranian general.

State TV described it early Wednesday as Tehran’s revenge operation over the killing of Revolutionary Guard Gen. Qassem Soleimani.

U.S. forces could not be immediately reached for comment.

State TV said the operation’s name was “Marytr Soleimani.” It said the Guard’s aerospace division, which controls Iran’s missile program, launched the attack.
