US won't 'stand by and watch sanctioned vessels', warns White House after tanker seized off Venezuela

The US will not "stand by and watch sanctioned vessels sail the seas", the White House has warned, after American forces seized an oil tanker off the coast of Venezuela.

Spokeswoman Karoline Leavitt told reporters she would not speak about future ship seizures, but said the US would continue to follow Donald Trump's sanction policies.

"We're not going to stand by and watch sanctioned vessels sail the seas with black market oil, the proceeds of which will fuel narcoterrorism of rogue and illegitimate regimes around the world," she said.

The US is gearing up to intercept more ships, six sources familiar with the matter told Reuters.

One source said several more sanctioned tankers had been identified by the US for potential seizure.

Two of the people said the US Justice Department and Homeland Security had been planning the seizures for months.

American forces were monitoring vessels in Venezuelan ports and waiting for them to sail into international waters before taking action, one source added.

It comes after a crude oil tanker, named Skipper, on Wednesday was stormed by US forces executing a seizure warrant.

The ship left Venezuela's main oil port of Jose between 4 and 5 December after loading about 1.1 million barrels of oil, according to satellite information analysed by TankerTrackers.com and internal shipping data from Venezuelan state oil company PDVSA.

US attorney general Pam Bondi said on X, formerly Twitter, that the ship was "used to transport sanctioned oil from Venezuela and Iran".

"For multiple years, the oil tanker has been sanctioned by the United States due to its involvement in an illicit oil shipping network supporting foreign terrorist organisations," she added.

Ms Leavitt said that "the United States does intend to get the oil" that was onboard the vessel.

The government in Caracas, led by President Nicolas Maduro, branded the ship's seizure a "blatant theft" and an "act of international piracy".

Why tanker seized by US was 'spoofing' its location

The US has been ramping up the pressure on Mr Maduro and is reportedly considering trying to oust him. It has piled on sanctions, carried out a military build-up in the southern Caribbean, and launched attacks on suspected drug vessels from Venezuela.

Now America has issued new sanctions targeting Franqui Flores, Efrain Antonio Campo Flores, and Carlos Erik Malpica Flores - three nephews of Mr Maduro's wife, Cilia Flores - as well as on six crude oil tankers and six shipping companies linked to them.

By seizing oil tankers, the US is threatening Mr Maduro's government's main revenue source - oil exports.

The sources said the US was focusing on what's been called the shadow fleet - tankers transporting sanctioned oil to China, the biggest buyer of crude from Venezuela and Iran.

They said one shipper had already temporarily suspended three voyages transporting six million barrels of Venezuelan crude oil.

"The cargoes were just loaded and were about to start sailing to Asia," a source said.

"Now the voyages are cancelled and tankers are waiting off the Venezuelan coast as it's safer to do that."
