The latest strike was the first in nearly three weeks. It comes as the Pentagon and the White House have struggled to answer questions about the legal basis for the campaign to kill suspected drug smugglers with military strikes, with US lawmakers promising to investigate the first such attack, in September, in which two survivors clinging to wreckage were killed in a follow-on strike.

Hegseth has faced increasing scrutiny over the 2 September strike following a report from the Washington Post that the defense secretary had verbally directed the military to "kill them all". On Thursday, a Democratic lawmaker introduced articles of impeachment against Hegseth, pointing to the boat strike and a report that found he broke rules by sharing information about an attack on Signal, but such an effort is unlikely to succeed.
