U.S. military conducted airstrikes against Houthi rebel targets in Yemen, including the destruction of an unmanned underwater vessel.

This marks the first instance of an underwater drone being used by the Houthis in the conflict, showcasing advanced maritime warfare technology.

The strikes were a response to Houthi attacks on U.S. and international commercial ships in the Red Sea, using sophisticated drone and missile systems.

Iran is accused of providing support to the Houthi rebels, though it reportedly does not exercise direct control over the group.

The conflict's escalation coincides with the Israel-Hamas war, influencing broader regional military responses.

The Biden administration intends to re-designate the Houthi rebels as a 'foreign terrorist organization' due to their terrorist acts.
