The US military killed three men in a strike on a suspected drug vessel in international waters in the Caribbean on Thursday, US Defense Secretary Pete Hegseth said.

Hegseth, said in a post on social media website X that the vessel was operated by a "Designated Terrorist Organization" but provided no further evidence. His post included a 20-second video clip, marked unclassified, of a boat in the water that gets struck by a munition and explodes.
