United States and Iranian forces exchanged military strikes on Monday in what each country labeled “self-defense” and retaliatory strikes.

U.S. Central Command announced the military launched “self-defense strikes” against Iran over the weekend, strategically targeting drone “radar and command and control sites.” The military said it conducted operations in designated areas in Qeshm Island and Goruk, Iran, in a social media post late Sunday night. Iranian forces claimed it fired “retaliatory” strikes in response, according to the Associated Press. Additionally, Kuwait announced it was engaged in defensive military operations as well, saying the country’s defenses had intercepted drones and missiles believed to be from Iran.

“The measured and deliberate strikes occurred on Saturday and Sunday in response to aggressive Iranian actions that included the shootdown of a U.S. MQ-1 drone that was operating over international waters,” said U.S. Central Command in a social media post late Sunday night. “U.S. fighter aircraft swiftly responded by eliminating Iranian air defenses, a ground control station, and two one-way attack drones that posed clear threats to ships transiting regional waters.”
