Aug. 25 (UPI) -- The U.S. military killed four people Tuesday in its latest strike targeting an alleged drug-trafficking boat in the Caribbean, the second strike in a matter of days after a two-month pause.

U.S. Southern Command has killed at least 227 people in 68 publicly acknowledged strikes targeting alleged drug-trafficking boats in the Caribbean and Pacific since the first strike on Sept. 2, according to UPI's tally, which is based on SOUTHCOM press releases.

As with previous strikes, SOUTHCOM said intelligence confirmed the boat it struck Tuesday was involved in narco-trafficking and that it was "operating along established narco-trafficking routes in the Caribbean."

As it has done with previous strikes, SOUTHCOM did not provide proof.

A seven-second aerial video of the strike published online by SOUTHCOM shows a boat driving along the water before it is enveloped in a flash.
