A United Nations human-rights expert has raised serious legal concerns over U.S. military strikes against suspected drug-trafficking vessels in the Caribbean and eastern Pacific, saying the operations may constitute crimes against humanity.
The UN special rapporteur on extrajudicial, summary or arbitrary executions said there were “reasonable grounds to believe” that the attacks violated international law and the right to life. The findings were reported Tuesday as international scrutiny intensified following another U.S. strike in the Caribbean that killed four people.
According to the UN expert’s findings, U.S. forces have conducted 68 attacks against suspected drug-trafficking boats since September 2025, with at least 223 people killed. Other reporting places the death toll even higher, depending on how subsequent strikes are counted.
Washington Defends Operations
The Trump administration has described the vessels as part of drug-trafficking networks and has defended the strikes as part of an effort to prevent narcotics from reaching the United States.
The administration has characterized the targets as “narco-terrorists” and argued that the operations are justified as an armed conflict against drug cartels.
The UN assessment challenges that legal justification, arguing that suspected drug trafficking by itself does not automatically permit lethal military force against individuals aboard a vessel.
The issue is particularly sensitive in the Caribbean, where the United States has conducted several of the operations.
Latest Strike Killed Four
The latest reported strike occurred Saturday, September 19, when U.S. forces attacked a suspected drug-trafficking vessel in the Caribbean, killing four people, according to U.S. Southern Command.
The military said the vessel was operating along established narco-trafficking routes.
The UN report adds another layer to an increasingly contentious debate over whether suspected drug trafficking can lawfully be treated as a basis for military action at sea.
The findings do not themselves constitute a judicial determination of criminal responsibility. Any formal determination of individual or state responsibility would require appropriate legal proceedings.
The dispute nevertheless places the Caribbean at the centre of a major international debate over the use of military force, maritime law, human rights and counter-narcotics operations.
