WASHINGTON - The US military struck an alleged drug-trafficking boat in the eastern Pacific on Tuesday, marking the third consecutive day of such operations and killing four men on board, the US Southern Command said.

"Intelligence confirmed the vessel was transiting along known narco-trafficking routes in the Eastern Pacific and was engaged in narco-trafficking operations," said the command on social platform X.

"Four male narco-terrorists were killed during this action. No US military forces were harmed," it added, without providing evidence that the vessel was ferrying drugs.

US forces sank two suspected drug-trafficking boats in the Eastern Pacific in the past two days, killing seven people in total, the command said.

Since early September, the US military has conducted roughly 50 known airstrikes on suspected drug-trafficking boats and killed at least 174 people aboard.

The Inter-American Commission on Human Rights held the first hearing of its kind in Guatemala City last month on the legality of US boat strikes in the Caribbean and the harm they are causing communities across Latin America, according to the American Civil Liberties Union, a major civil rights group in the United States.
