The U.S. military said that it killed four "narco-terrorists" in an airstrike strike on an alleged drug-smuggling boat in the Caribbean.

Sept. 20 (UPI) -- The U.S. military said it killed four "narco-terrorists" in an airstrike on an alleged drug-smuggling boat in the Caribbean.

U.S. Southern Command said Saturday that Joint Force Western Hemisphere "executed a lethal, kinetic strike on a go-fast vessel operating along established narco-trafficking routes in the Caribbean."

SOUTHCOM didn't disclose the exact location of the strike.

Video footage released by SOUTHCOM showed what appeared to be a moving boat followed by a flash.

"Confirmed intelligence revealed the vessel's active involvement in narco-trafficking," SOUTHCOM continued, adding that the four people killed were "narco-terrorists."

The operation is the 69th strike on "narco-terrorists" over the past year. At last, 231 individuals have been killed

SOUTHCOM did not provide evidence that the vessel had been carrying drugs.

The Trump administration has designated several gangs as terrorist organizations, including Venezuela's Tren de Aragua, the Sinaloa Cartel and the Mexican cartel known as the Jalisco New Generation Cartel.
