Iran vows to “punish” the United States after the U.S. military says it has completed a “heavy wave of strikes” overnight against targets in Iran. Both outlets describe the U.S. action as retaliation for an earlier attack by Tehran on U.S. forces in the Middle East.

NBC News reports that Iran’s threat comes on Thursday, framed as a response to the overnight strikes. The Hill similarly reports that Iranian officials, including the Revolutionary Guard, state they will punish the “aggressor” and extend the warning beyond the U.S. itself.

According to The Hill, Iran’s messaging also targets Gulf countries that support Washington in the conflict, warning that they could be included in any Iranian response. The reporting characterizes the exchange as part of an ongoing cycle of attacks and counterattacks between Iran and U.S. forces in the region, with each side citing prior actions as justification for the latest move.

The sources do not provide additional confirmed details on casualties, specific locations hit, or the scope of damage beyond the characterization of the strikes as a “heavy wave.”
