The latest U.S. military strike on a boat accused of ferrying drugs in the eastern Pacific Ocean killed three people Sunday, according to a social media post by U.S. Southern Command.

The Trump administration’s campaign of blowing up alleged drug-trafficking vessels in Latin American waters has gone on since early September and killed at least 186 people in total. Other strikes have taken place in the Caribbean Sea.

The military has not provided evidence that any of the vessels were carrying drugs.

When asked about a previous strike in the eastern Pacific that killed two men, a spokesperson for U.S. Southern Command told CBS News: “For operational security reasons, we cannot discuss specific sources or methods.”

After Sunday’s attack, Southern Command posted a video on X showing a boat moving swiftly in the water before an explosion left it in flames. It repeated previous statements by saying it had targeted the alleged drug traffickers along known smuggling routes.

The attacks began as the U.S. built up its largest military presence in the region in generations and came months ahead of the raid in January that captured then-Venezuelan President Nicolás Maduro. He was brought to New York to face drug trafficking charges and has pleaded not guilty.

The campaign has ramped up again in recent weeks, with at least eight boat strikes in the Caribbean and eastern Pacific so far this month.

President Trump has said the U.S. is in “armed conflict” with cartels in Latin America and has justified the attacks as a necessary escalation to stem the flow of drugs into the United States.

Critics, meanwhile, have questioned the overall legality of the boat strikes.
