France & UK Board Russian Oil Tanker: A Crackdown on the Shadow Fleet

French navy intercepts the Tagor in the Atlantic, aided by the UK, stopping a vessel that could be funneling oil money to Russia’s war.

In a joint operation with the United Kingdom, French forces boarded the Russian‑flagged tanker Tagor 400 nm west of Brittany. The vessel was part of Russia’s so‑called shadow fleet – a network of ships that dodge sanctions and supply funds to the Ukraine war. President Macron says the seizure followed maritime law and is a key step in preventing illegal oil trafficking.

French & UK Forces Seize Russian Oil Tanker

During a Sunday operation in the Atlantic, French naval officers boarded the tanker *Tagor*, which was flying a false flag. The ship is believed to belong to Russia’s “shadow fleet” – a covert network of tanker operators that keep Russian oil flowing past international sanctions.

México‑style President Emmanuel Macron tweeted that the move was carried out “in strict compliance with the law of the sea” and that it cut off money that fuels the war Russia has waged against Ukraine.

The UK’s Ministry of Defence confirmed that a helicopter from HMS Somerset tracked and monitored the vessel, offering critical support to the French operation.

The Tagor is already the fourth suspected shadow fleet ship that French authorities boarded since September last year. Together, the two nations say they will continue to target this illegal maritime activity.
