US President Donald Trump has posted a video purportedly showing dozens of Houthi fighters being killed in an American strike on Yemen, adding the comment “oops”.

“These Houthis gathered for instructions on an attack,” Trump wrote in an accompanying text, using an alternate spelling for the Yemeni rebel group.

“Oops, there will be no attack by these Houthis,” Trump wrote. “They will never sink our ships again!”

Resembling images shot from military drones or other loitering aircraft, the black-and-white footage Trump posted to his Truth Social network shows several dozen human figures from an almost vertical angle.

A few seconds in, a bright flash appears in the middle of the scene, followed by billowing smoke. The footage cuts to a wider shot showing a column of smoke over the apparent impact site and several vehicles parked further up the road. The camera then cuts closer again to show a broad crater at the point of impact. No bodies are readily identifiable.
