President Donald Trump announced that U.S. forces carried out a second military strike in two weeks against a boat he claimed was smuggling drugs from Venezuela, killing three people and leaving “bags of cocaine and fentanyl” in the ocean.

Trump framed the strike as part of his policy to treat drug cartels like foreign terrorist organizations, allowing the use of lethal force.

Critics, including Sen. Rand Paul, questioned the legality and morality of such actions, warning they could constitute war crimes.

Details about the strike, including how it was conducted, remain unclear.

Earlier this month, Trump said a similar strike killed 11 alleged smugglers, though Venezuela denied they were traffickers, ABC News has reported.

The operations come amid a major U.S. military buildup in the region, with Navy ships, fighter jets, and armed drones deployed under Trump’s orders.
