French Navy intercepts an oil tanker in the Med sailing from Russia

French Navy intercepts a sanctioned oil tanker sailing from Russi in the Medeterranean.

PARIS (AP/UNB) — France’s Navy, working with intelligence provided by the United Kingdom, on Thursday intercepted an oil tanker in the Mediterranean Sea that traveled from Russia, in a mission targeting the sanctioned Russian shadow fleet, officials said.

French maritime authorities for the Mediterranean said the ship, the Grinch, is suspected of operating with a false flag. The French Navy is escorting the ship to port for more checks, the statement said.

Oil revenue is a key part of Russia’s economy, allowing President Vladimir Putin to pour money into the war effort against Ukraine without worsening inflation for everyday people and avoiding a currency collapse.

France and other countries have vowed to crack down on the sanction-busting shadow fleet of oil tankers which experts estimate numbers over 400 ships. They are also trying to secure deals with flag-carrying countries to make it easier to board the vessels.

“We are determined to uphold international law and to ensure the effective enforcement of sanctions," French President Emmanuel Macron said in a post about the interception, with a photo showing a French helicopter hovering over a ship.

“The activities of the ‘shadow fleet’ contribute to financing the war of aggression against Ukraine,” Macron added.

The French mission was conducted together with the U.K, which gathered and shared intelligence that enabled the ship to be intercepted, according to French military officials who spoke to The Associated Press on condition of anonymity to discuss the operation.

The ship was flying under a false flag from the Comoros islands, which are off east Africa, and its crew is Indian, the officials said. It was intercepted in the western Mediterranean, off the southern Spanish coastal town of Almeria, the officials said.
