U.S. Southern Command said a joint task force carried out a lethal strike this week on a vessel in the Eastern Pacific that U.S. officials allege was involved in narcotics trafficking linked to designated terrorist organizations.

In a statement posted Friday, the command said that on Feb. 20, at the direction of SOUTHCOM commander Gen. Francis L. Donovan, Joint Task Force Southern Spear conducted a “lethal kinetic strike” on a vessel transiting along known drug-trafficking routes.

U.S. officials said intelligence indicated the vessel was engaged in narcotics trafficking operations. Three men described as “narco-terrorists” were killed during the action, according to the statement.

“No U.S. military forces were harmed,” the command said.

The statement did not provide details about the vessel’s flag, ownership, precise location or whether any contraband was recovered following the strike. It also did not identify the individuals killed.

U.S. Southern Command oversees military operations and security cooperation in Central and South America and the Caribbean. The operation was conducted under what officials described as ongoing counter-narcotics efforts in the region.

Further details were not immediately available.
