() President Donald Trump has ordered the United States military to “launch decisive and powerful” action against the Iran-backed Houthis in Yemen.

Trump made the announcement during a lengthy Truth Social post where he criticized former President Joe Biden’s response to the group, and warned Iran they will face consequences should they continue to support the Houthis.

“Our brave Warfighters are right now carrying out aerial attacks on the terrorists’ bases, leaders, and missile defenses to protect American shipping, air, and naval assets, and to restore Navigational Freedom,” Trump said in the post. “No terrorist force will stop American commercial and naval vessels from freely sailing the Waterways of the World.”

“Funded by Iran, the Houthi thugs have fired missiles at U.S. aircraft, and targeted our Troops and Allies. These relentless assaults have cost the U.S. and World Economy many BILLIONS of Dollars while, at the same time, putting innocent lives at risk.”

The Houthis reported a series of explosions in their territory Saturday evening. Images circulating online show plumes of black smoke over the area of the Sanaa airport complex, which includes a sprawling military facility. The extent of the damage was not yet clear.

The airstrikes come a few days after the Houthis said they would resume attacks on Israeli vessels sailing in waters off Yemen in response to Israel’s blockade on Gaza. There have been no Houthi attacks reported since then.

The Trump administration formally labeled the Houthis as a “foreign terrorist organization” again last month following Biden’s revocation of the title during his term.

“To all Houthi terrorists, YOUR TIME IS UP, AND YOUR ATTACKS MUST STOP, STARTING TODAY. IF THEY DON’T, HELL WILL RAIN DOWN UPON YOU LIKE NOTHING YOU HAVE EVER SEEN BEFORE!” Trump added.

“To Iran: Support for the Houthi terrorists must end IMMEDIATELY! Do NOT threaten the American People, their President, who has received one of the largest mandates in Presidential History, or Worldwide shipping lanes. If you do, BEWARE, because America will hold you fully accountable and, we won’t be nice about it!”
