WASHINGTON (AP) — The U.S. military said it killed three people Monday in a strike on an alleged drug-smuggling vessel in the Caribbean Sea as part of the Trump administration’s monthslong campaign against alleged traffickers.

Monday’s attack brought the death toll to at least 151 people since the Trump administration began targeting those it calls “narcoterrorists” in small vessels in early September.

As with most of the military’s statements on the more than 40 known strikes, U.S. Southern Command said it targeted alleged drug traffickers along known smuggling routes. The military did not provide evidence that the vessel was ferrying drugs but posted a video on X that showed a small boat with outboard engines being destroyed.

“Intelligence confirmed the vessel was transiting along known narco-trafficking routes in the Caribbean and was engaged in narco-trafficking operations,” Southern Command stated in a post on X. “Three male narco-terrorists were killed during this action.”

President Donald 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. But his administration has offered little evidence to support its claims of killing “narcoterrorists.”

Critics have questioned the overall legality of the strikes as well as their effectiveness, in part because the fentanyl behind many fatal overdoses is typically trafficked to the U.S. over land from Mexico, where it is produced with chemicals imported from China and India.

The boat strikes also drew intense criticism following the revelation that the military killed survivors of the very first boat attack with a follow-up strike. The Trump administration and many Republican lawmakers said it was legal and necessary, while Democratic lawmakers and legal experts said the killings were murder, if not a war crime.
