U.S. Seizure of the Russian-flagged "Marinera" Oil Tanker (2026)

The United States seizure of the Russian-flagged tanker “Marinera” is a maritime operation conducted on 7 January 2026 in the North Atlantic. U.S. European Command stated that the operation targeted a vessel violating U.S. sanctions. The tanker had previously operated under the name “Bella 1” and has been subject to U.S. sanctions since 2024 over allegations of illicit oil transportation linked to Venezuela.

The U.S. Department of Justice, in coordination with the Department of Homeland Security and the Department of Defense, carried out the operation under the “Strategy to Halt Illicit Oil Shipments in the Western Hemisphere” initiative of the administration of U.S. President Donald Trump. Prior to the operation, the “Marinera” evaded tracking by the U.S. Coast Guard for approximately two weeks, moving northeast until it was detected near Iceland.

The tanker obtained temporary registration under Russian law and a Russian flag on 24 December 2025. Following the U.S. seizure, the Russian Ministry of Transport declared the operation a violation of international law, with the Moscow government characterizing it as an act contrary to the United Nations Convention on the Law of the Sea (1982).

On 9 January 2026, Russian Foreign Ministry Spokesperson Maria Zaharova announced that, under President Donald Trump’s orders, two Russian citizens from the “Marinera” crew would be released.

Course of the Operation

U.S. forces seized the Russian-flagged “Marinera” tanker in the North Atlantic on 7 January 2026. The operation was jointly conducted by the U.S. Department of Justice, Department of Homeland Security, and Department of Defense. The U.S. European Command (EUCOM) confirmed the operation was carried out on the grounds of “violation of U.S. sanctions.”

The USCGC Munro, a vessel of the U.S. Coast Guard, carried out the tracking and boarding of the tanker. U.S. Navy Special Forces (Navy SEALs) boarded the vessel by helicopter, while the U.S. Army’s 160th Special Operations Aviation Regiment (Night Stalkers) provided aerial support during the operation.

The seizure occurred in international waters approximately 190 miles south of Iceland’s coast. Following the operation, U.S. Secretary of Defense Pete Hegseth stated, “The blockade on sanctioned and illicit Venezuelan oil is having full global effect.”

U.S. Secretary of Homeland Security Kristi Noem made the following statement on her social media account: “Today, prior to dawn, the Coast Guard executed two meticulously coordinated back-to-back operations targeting two ‘ghost fleet’ tankers.” Noem added, “The world’s criminals have been warned. You can run, but you cannot hide.”

The operation received support from the United Kingdom, as confirmed by the UK Ministry of Defence. The statement read: “The United Kingdom supported the intervention against the vessel Bella 1 at the request of the United States.”

UK Defence Secretary John Healey stated in the official announcement: “The United Kingdom’s armed forces demonstrated professionalism by successfully supporting the interdiction of a Russian-flagged vessel in the North Atlantic.”

U.S. Attorney General Pam Bondi said after the operation: “Despite intense efforts to evade capture, U.S. forces successfully secured the vessel.” Regarding the crew, Bondi added: “The crew of the vessel is under full investigation for failing to comply with U.S. Coast Guard orders, and criminal proceedings will be initiated against all responsible individuals.”

No confrontation occurred aboard the vessel during the operation. The U.S. Southern Command (SOUTHCOM) stated: “The seized M/T Sophia was operating in international waters and engaged in illicit activities in the Caribbean Sea.” U.S. military assets stationed between the United Kingdom, Iceland, and Greenland provided operational support, with Royal Air Force reconnaissance aircraft and the RFA Tideforce vessel delivering logistical support.

Russia’s Response and Diplomatic Process

The Russian Ministry of Transport classified the U.S. seizure of the “Marinera” tanker as a violation of the United Nations Convention on the Law of the Sea (1982). The ministry’s written statement read: “Under the 1982 UN Convention on the Law of the Sea, freedom of navigation on the high seas applies, and no state has the right to use force against vessels lawfully registered under another state’s flag.”

The statement further noted that the vessel had received temporary permission to sail under the Russian flag on 24 December 2025 and added: “U.S. naval forces ceased all communication with the vessel immediately after approaching it on the high seas, outside any state’s territorial waters.”

Russian State Duma member Leonid Slutskiy described the seizure as a “21st-century act of piracy.” The Russian Ministry of Defence reported that it had deployed a submarine and other naval assets to the area prior to the seizure to ensure the vessel’s safety. According to Reuters, Russian naval units were present at the time of the incident but no confrontation occurred.

In another statement, the Russian Foreign Ministry said: “For reasons incomprehensible to us, the Russian vessel is receiving increasing attention from U.S. and NATO forces — attention that is clearly disproportionate to the vessel’s peaceful status.”

The Russian Foreign Ministry confirmed the presence of Russian citizens aboard the seized vessel and called for respect of their rights. The ministry’s statement added: “The rights of Russian citizens aboard the vessel must be respected. The United States must not prevent the Russian citizens aboard the ‘Marinera’ from returning to their homeland.”

On 9 January 2026, Russian Foreign Ministry Spokesperson Maria Zaharova announced that U.S. President Donald Trump had decided to release two Russian crew members from the “Marinera” seized in the North Atlantic. Zaharova stated: “At our request, U.S. President Donald Trump has decided to release two Russian citizens from the crew of the ‘Marinera’ tanker who were taken into custody by U.S. forces during the operation.”

Zaharova also noted that preparations were underway to return the released individuals to Russia. The Moscow government stated it “welcomed the decision” and expressed gratitude to the U.S. administration.

International Reactions and Legal Dimensions

United Nations (UN) Spokesperson Stephane Dujarric, in his statement regarding the U.S. seizures of two oil tankers in the North Atlantic and the Caribbean, said the UN is closely monitoring the situation. Dujarric stated: “Our current position is that all law enforcement actions on the oceans and seas to ensure maritime security must be conducted in accordance with applicable international law.”

Dujarric, expressing a desire to prevent further escalation, also commented on the U.S. claim that it would control Venezuelan oil: “Our longstanding position as the UN is clear: oil from Venezuela belongs to the Venezuelan people, just as oil from Syria belongs to the Syrian people. The natural resources of any country belong to its people.”

Chinese Foreign Ministry Spokesperson Mao Ning, at a press briefing in Beijing, stated regarding the U.S. actions: “China has always opposed unlawful unilateral sanctions lacking a basis in international law and not approved by the UN Security Council.” Mao added: “We oppose any action that violates the purposes and principles of the UN Charter and undermines the sovereignty and security of other countries.”

White House Press Secretary Karoline Leavitt stated: “The vessel was deemed stateless due to its use of a false flag and is therefore subject to judicial interdiction.” Defence Secretary John Healey affirmed that the operation was conducted in full compliance with international law, stating: “The United Kingdom’s armed forces acted in strict accordance with international law.”

Identity and Operational History of the “Marinera” Tanker

“Marinera” is known to have previously operated under the name “Bella 1”. Since 2024, the vessel has been subject to U.S. sanctions over allegations of illicit oil transportation. It has been reported to be part of a sanctioned evasion network known as a “shadow fleet,” transporting oil originating from Venezuela.

The U.S. Coast Guard first attempted to intercept the vessel in December 2025, but the effort failed when the crew changed course and headed toward the Atlantic Ocean. During this period, the crew painted the Russian flag on the hull, renamed the vessel “Marinera,” and obtained temporary registration under the Russian flag. The Russian Ministry of Transport confirmed the vessel received its sailing permit under Russian Federation regulations on 24 December 2025.

U.S. authorities described the vessel as “stateless” and claimed it was sailing under a false flag, which they cited as the legal basis for their intervention under international maritime law.

Satellite tracking data shows that the “Marinera” vessel disabled its AIS (Automatic Identification System) twice for extended periods, temporarily concealing its identity and location.

The U.S. European Command stated that during the seizure, the vessel was not carrying cargo. U.S.-based energy analytics firm Kpler confirmed that at the time of seizure, the “Marinera” was not transporting crude oil, but had previously departed from Venezuelan ports for shipment.

The Russian side stated that the “Marinera” is registered in Sochi and was sailing in full compliance with international maritime law under the Russian flag. After the U.S. seizure, the Russian Ministry of Transport confirmed that communication with the vessel had been lost.
