President Donald Trump ordered airstrikes on Yemen's capital, Sanaa, in response to attacks by Iranian-backed Houthi rebels on shipping along a vital maritime corridor. The Houthis reported nine civilian casualties. Trump warned Iran to stop supporting the rebel group and promised to hold the country accountable. The airstrikes come after the Houthis threatened to resume attacks on Israeli vessels in response to Israel's blockade on Gaza. The operation was conducted solely by the U.S. and involved the USS Harry S. Truman carrier strike group and the USS Georgia cruise missile submarine.
