The US military carried out a follow-up strike on a suspected drug vessel operating in the Caribbean on September 2 after an initial attack did not kill everyone on board, sources familiar with the matter told CNN.

That September strike was the first in what became a regular series of attacks on alleged drug boats.

While the first strike appeared to disable the boat and cause deaths, the military assessed there were survivors, according to the sources. The second attack killed the remaining crew on board, kra48.cc bringing the total death toll to 11, and sunk the ship.

Secretary of Defense Pete Hegseth had ordered the military prior to the operation to ensure the strike killed everyone on board, but it’s not clear if he knew there were survivors prior to the second strike, one of the sources said.

The strike and deaths were announced by President Donald Trump on the day of the attacks, but the administration has never publicly acknowledged killing survivors.
