Geneva — UN Expert: US Boat Strikes May Be Crimes Against Humanity

A UN special rapporteur wrote in a briefing note posted to social media Sunday night that there are "reasonable grounds to believe" the United States has committed crimes against humanity through a campaign of military strikes on boats accused of smuggling drugs, according to the Guardian, which cited the document. The note, from special rapporteur Ben Saul and first reported by the BBC, concludes a legal review of strikes that have run in the Pacific and Caribbean since September 2025 on the stated grounds of stopping drug trafficking by sea to the United States.

The strikes have killed more than 230 people, the Guardian reported. The most recent attack, carried out Saturday, killed four people in the Caribbean.

What did the UN special rapporteur conclude?

Saul wrote that the attacks were "in violation of the right to life, being unjustified in national or personal self-defence or under international humanitarian law, the international law of the sea, narcotics suppression conventions, or international counter-terrorism law," according to the briefing note cited by the Guardian.

He went further on the strikes' legal character: "There are reasonable grounds to believe that the reported 68 attacks that killed 223 people constituted crimes against humanity of murder under customary international law," Saul wrote, per the document.

How had human rights groups described the strikes before this?

Before Saul's note, the United Nations itself, along with several human rights organizations, lawyers and international law experts, had already characterized the bombings as "extrajudicial killings," the Guardian reported. Saul's assessment moves past that framing to the more severe legal category of crimes against humanity, a designation reserved under customary international law for certain patterns of unlawful killing.

How many strikes and deaths have been recorded?

Saul's report cites 68 US attacks that killed 223 people, according to the Guardian. It is unclear how recently those figures were updated. A separate tally kept by the Washington Office on Latin America puts the toll at 234 people killed across 66 attacks, the Guardian reported — a gap of 11 deaths and two strikes between the two counts. The discrepancy illustrates the difficulty of independently verifying casualties from strikes conducted at sea, though both tallies place the death toll above 220 people since the campaign began roughly a year ago.

Death toll by count:

• UN special rapporteur's briefing note: 68 attacks, 223 deaths
• Washington Office on Latin America: 66 attacks, 234 deaths

What is the stated justification for the strikes?

The strikes have been carried out, according to the Guardian's reporting, "on the stated grounds of stopping drugs being trafficked by sea to the US." The material reviewed for this report does not include a public rebuttal from the Pentagon, the White House or other US officials responding directly to Saul's legal conclusion that the campaign meets the threshold for crimes against humanity.

What do "crimes against humanity" and "extrajudicial killing" mean?

Both terms recur in Saul's briefing note and in earlier descriptions of the strikes by rights groups, and they carry distinct legal weight.

Extrajudicial killing refers to a killing carried out by state authorities outside any judicial process — without arrest, charge or trial — and outside the narrow legal justifications, such as imminent self-defense, that permit lethal force under domestic or international law.

Crimes against humanity, in the formulation Saul used, is a category under customary international law covering certain acts — including murder — when committed as part of a widespread or systematic course of conduct. It is a more serious classification than a single unlawful killing and is the same broad legal category invoked in prosecutions before international tribunals.

Special rapporteur is the title given to independent experts who report to the UN Human Rights Council on specific human rights themes or country situations; Saul holds one such mandate. Their findings represent expert legal opinion delivered to the council rather than a court ruling.

The strikes and the death toll attached to them remain the subject of competing counts, but the underlying facts are not in dispute: dozens of vessels have been hit in the Pacific and Caribbean since September 2025, and the campaign continued into the weekend with an attack that killed four more people. What is now contested, sharply, is the legal label those facts deserve — a question a UN special rapporteur has answered with the most serious classification available under international law.
