US Seizes Russian-Flagged Oil Tanker Linked to Venezuela in North Atlantic Raid

Seizure of Russian-flagged tanker

U.S. forces seized a Russian-flagged oil tanker identified as the Marinera (formerly Bella-1) in the North Atlantic after a weeks-long pursuit, part of what U.S. officials describe as a 'shadow' or 'ghost fleet' moving sanctioned oil for Venezuela, Russia and Iran.

The operation was announced as one of two interdictions; the second took place in Caribbean international waters, and U.S. European Command and Homeland Security said the North Atlantic boarding followed earlier attempts to stop the vessel near Venezuela.

U.S. officials say the ship had been tracked by the Coast Guard, renamed and reflagged while crossing the Atlantic, and was taken under a U.S. federal court warrant for alleged sanctions violations.

Flag-state seizure dispute

The seizure prompted an immediate dispute over flag-state rights and maritime law.

Russian authorities protested, citing the U.N. Convention on the Law of the Sea and saying the Marinera had been granted temporary permission to sail under the Russian flag on Dec. 24.

Russian officials called the boarding and seizure a violation of international law.

U.S. and allied statements said the ship had at times been effectively stateless, accused it of previously flying false flags, and cited a U.S. federal court order as legal authority for the boarding and seizure.

Military and surveillance reports

Reports differ over the military and surveillance activity that accompanied the operation. Multiple outlets say U.S. aircraft, special-operations teams and the Coast Guard tracked and boarded the vessel.

Several reports say Russian naval units, including a submarine and a warship, were in the area, though there was no reported clash. Coverage ranges from detailed accounts of aircraft and base movements to shorter, measured notices emphasizing that no direct firefight occurred.

U.S. interdictions on Venezuelan oil

U.S. officials framed the interdictions as part of a sustained policy to halt sanctioned Venezuelan oil shipments and deny revenue to the Maduro government. Senior U.S. officials said the blockade remains in effect globally.

The White House and other U.S. agencies described the vessels as part of a 'shadow' or 'dark' fleet. U.S. spokespeople outlined plans to sell or control proceeds from seized oil to benefit Venezuelans and further U.S. policy goals.

Marinera seizure uncertainties

Key facts about the ship's cargo, ownership and ultimate destination remain unclear in public reporting. Several outlets note the Marinera had been sanctioned in 2024 over alleged smuggling tied to a firm with links to Hezbollah and had a recent voyage history involving Iran, Venezuela and a listing to Russian ports; others say the vessel was empty when seized. Estimates and commentary about potential cargo transfers or dark ship-to-ship moves vary across reports, leaving open questions about why a large interdiction occurred far from Venezuela and what the seized vessel (and a companion ship) would yield financially or legally.
