France’s navy intercepted the oil tanker Tagor in international waters on May 31, boarding the vessel via helicopter roughly 400 nautical miles west of Brittany. French President Emmanuel Macron announced the operation on June 1, framing it as a direct strike against Russia’s sprawling shadow fleet.
The Tagor, identified by IMO number 9282481, was ordered to a French port for inspection. Authorities cited concerns over the vessel’s registration and allegations it was operating under a false flag to facilitate illegitimate Russian oil exports.
A growing pattern of enforcement
The Tagor seizure marks the third time French authorities have seized a sanctioned tanker linked to Russia in recent months. The US sanctioned the vessel on July 30, 2025. The EU followed on October 24, 2025. The UK added its own designation in February 2026.
Among the allegations: the Tagor manipulated its Automatic Identification System signals to obscure routes and disguise ship-to-ship transfers of Russian crude. The vessel had previously been involved in operations out of Russia’s Murmansk port. UK forces collaborated with the French navy on the interception.
