Sept. 15 (UPI) -- President Donald Trump said Monday the military killed three members of what he called a Venezuelan drug cartel transporting illegal narcotics across international waters to the United States.

Trump made the announcement in a social media post that described the attack as a warning and included a video of the military strike on the boat allegedly carrying drugs. The strike comes roughly two weeks after Trump announced a similar attack that marked an escalation in the president's unconventional and bellicose campaign against drug traffickers.

"If you are transporting drugs that can kill Americans, we are hunting you!" Trump wrote in the post, much of which was in all caps. "The illicit activities by these cartels have wrought devastating consequences on American communities for decades, killing millions of American citizens."

The post did not include details about the location of strike, only noting it was in the military's Southcom area of responsibility, which encompasses South America. The post also did not name the cartel of which the men killed in the strike allegedly were affiliated, but the president called them "confirmed narcoterrorists from Venezuela.

The video accompanying the video lasts less than 30 seconds and shows a boat floating above the waves before a bright flash and explosion. The video then shows smoke and flames billowing from the boat.
