"The remaining narco-terrorists abandoned the other two vessels, jumping overboard and distancing themselves before follow-on engagements sank their respective vessels.".
U.S. Southern Command said it targeted three vessels traveling in a convoy in undisclosed international waters.
At least six people survived the Dec. 30 strikes, which took place in the Eastern Pacific, according to a U.S. official.
The U.S. Coast Guard was notified to begin searching for the survivors in a search and rescue operation, the statement said.
The U.S. Coast Guard confirmed that a search-and-rescue operation was underway, and that Coast Guard C-130 aircraft had been deployed for the operation.
Several hours after announcing the Dec. 30 strikes, Southern Command posted on social media that another series of strikes -- carried out on New Year's Eve -- had targeted two more vessels alleged to be engaged in drug trafficking.
The U.S. campaign targeting alleged drug boats came under scrutiny last month after the Trump administration acknowledged survivors of an initial series of strikes on an alleged drug vessel on Sept. 2 were killed in a follow-up series of strikes. »
