The United States conducted five self-defense strikes in areas of Yemen controlled by the Iranian-backed Huthi militias, U.S. Central Command said on February 18. It said it struck three mobile, anti-ship cruise missiles, one unmanned underwater vessel, and one unmanned surface vessel on February 17. Huthi attacks in the Red Sea area have been one sign of spreading conflict in the Middle East since war erupted between Israel and Hamas -- deemed a terrorist organization by the United States and European Union -- after the extremist Palestinian group's deadly assault on Israel on October 7.
