A top US Navy commander ordered a second round of military strikes on an alleged Venezuelan drug boat, the White House has confirmed.

Admiral (Frank) Bradley worked well within his authority and the law in ordering the additional strike, White House Press Secretary Karoline Leavitt said on Monday.

Leavitt confirmed Defence Secretary Pete Hegseth authorised the strikes but did not give an order to kill everybody, as the Washington Post reported. The second strike was reportedly executed after two people survived the initial blast and were clinging to the burning vessel.

Both Republican and Democratic lawmakers have expressed concern over the report and vowed congressional reviews of the strikes.

President (Donald) Trump and Secretary Hegseth have made it clear that presidentially designated narco-terrorist groups are subject to lethal targeting in accordance with the laws of war, Leavitt added during her Monday briefing.

Experts have raised serious doubts about the legality of attacking alleged survivors, arguing they may have been protected as shipwrecked individuals. The Trump administration has framed its operations in the Caribbean as part of a non-international armed conflict with drug traffickers, which comes with its own set of rules as defined by the Geneva Conventions.

Amid these developments, tensions between the US and Venezuela have increasingly escalated, with the Trump administration accusing the Venezuelan government of harboring narco-terrorists and expressing interest in deploying ground forces in the country.

As concerns over legality and ethics rise, ongoing congressional oversight aims to gather critical insights on these military actions and their implications for international law and relations.
