Houthis post cryptic video of American flag-draped coffins

"These terrorists really cannot tell the difference between delusions and reality," Hussain Abdul-Hussain, a research fellow at the Foundation for Defense of Democracies (FDD), said in a post on X along with the Houthi animation.

The animation starts out with somber music and depicts a coffin draped in an American flag floating in water, then slowly zooms out to reveal dozens of similar flag-draped coffins floating away from destroyed warships.

"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!" 

"President Trump is taking action against the Houthis to defend US shipping assets and deter terrorist threats," the White House wrote in a post on X. "For too long American economic & national threats have been under assault by the Houthis. Not under this presidency."

U.S. Central Command said in a statement Saturday that it "initiated a series of operations consisting of precision strikes against Iran-backed Houthi targets across Yemen to defend American interests, deter enemies, and restore freedom of navigation."

Meanwhile, the Houthi-run Health Ministry in Yemen told the Associated Press that the strikes killed at least 31 people.
