The US military opened fire on Houthi rebels after they attacked a cargo ship in the Red Sea, resulting in casualties. The Houthis acknowledged their fighters' deaths and warned of consequences. The USS Gravely destroyer shot down missiles fired at the Maersk Hangzhou and later responded to the cargo ship's distress call. US Navy helicopters returned fire on the attackers, sinking three of their boats. This incident marks the 23rd Houthi attack on international shipping since November 19 and the first time US personnel have killed Houthi fighters in the Red Sea attacks.
