President Donald Trump says the United States will hold Iran responsible for any future attacks by Yemen’s Houthi rebels on ships transiting the Red Sea. In a post on Truth Social, Trump states that the Houthis act as a surrogate or proxy for Iran and that the U.S. would respond with “major military punishment” if the group carries out additional attacks. He links the warning to a reported Houthi strike the night before involving two Saudi Arabian oil tankers in the Red Sea. Several outlets report that the Houthis claimed responsibility, saying they hit the vessels after they violated a claimed naval blockade, and that the attacks caused additional ships to retreat. Reuters and related reporting are not included in the provided excerpts, but the articles cite that U.S. forces previously attacked the Houthis in March to May 2025 following similar interference with commerce and trade. Trump’s message is framed as a continuation of past U.S. actions and as a deterrent against renewed Houthi attacks affecting commercial shipping and U.S. allies in the region.
