A U.S. military strike in the Eastern Pacific killed three individuals aboard a suspected drug-trafficking vessel, according to U.S. Southern Command (SOUTHCOM).

The strike was carried out on Friday at the direction of SOUTHCOM commander Gen. Francis L. Donovan. In a statement, the command said the vessel was operated by a Designated Terrorist Organization and was transiting along known narcotics trafficking routes.

“Intelligence confirmed the vessel was transiting along known narco-trafficking routes in the Eastern Pacific and was engaged in narco-trafficking operations,” SOUTHCOM said.

The three individuals killed were described by the military as “narco-terrorists.” SOUTHCOM reported that no U.S. personnel were injured during the operation.

The strike was conducted as part of Operation Southern Spear, a campaign launched in September targeting vessels allegedly linked to designated terrorist organizations involved in drug trafficking across the Caribbean and Eastern Pacific.

Since the campaign began, SOUTHCOM says at least 44 vessels have been struck, resulting in 143 deaths. Of those vessels, 31 were operating in the Pacific and 13 in the Caribbean.

Earlier this week, SOUTHCOM reported additional strikes in the Eastern Pacific and Caribbean targeting three vessels, with 11 individuals killed in those operations.
