The Biden administration announced on Wednesday the redesignation of the Yemen-based Houthis as a terrorist entity the same day the U.S. military carried out strikes against the Iranian-supported group.

Houthi forces have carried out more than 30 attacks on commercial vessels in the Red Sea since mid-November, threatening the global trade industry, in addition to posing lethal threats to every crew member on those ships. They have continued to launch these attacks in spite of international condemnation and limited but repeated military responses.
