The tanker Marinera and the Venezuela blockade
Summary
A retrospective on the seizure of a Russian-flagged vessel in the North Atlantic, reported on 7 January 2026 and still in the news on 8 January.
What did it mean when the United States seized a Russian-flagged tanker far from the Caribbean? By 8 January 2026, that question was live, after the boarding of the sanctioned vessel Marinera, also known as Bella 1, was reported on 7 January.
According to the reports, US forces boarded and seized the tanker in the North Atlantic Ocean. The vessel had breached the American naval blockade around Venezuela. The seizure was listed under Operation Southern Spear and touched on relations between Russia and the United States.
How the blockade began
The blockade itself was not new. The United States enacted it on 17 December 2025 against sanctioned oil tankers travelling to and from Venezuela, after imposing further sanctions that affected the country's oil trade. A week before the blockade was announced, on 10 December, US forces had seized the tanker Skipper off the Venezuelan coast in the Caribbean Sea. Washington then concentrated its military effort on intercepting and pursuing other vessels trading with Venezuela.
A wider reach
The Marinera boarding was notable for where it took place. Later accounts place the seizure in the Atlantic near Iceland. On the same day, 7 January, the United States also boarded the Panama-flagged M Sophia in the Caribbean Sea.
Together, the two seizures showed a blockade that was being enforced both in the Caribbean and across the Atlantic, and that now included a ship flying the Russian flag.
