France intercepts Russia-linked oil tanker near Sicily in shadow fleet crackdown

French special forces boarded the oil tanker Deliver in international waters near Sicily on Tuesday, in what Paris described as the country's latest move to disrupt the so-called Russian shadow fleet. President Macron published video of the operation on social media, showing heavily armed personnel landing on the vessel's deck from a helicopter.

The operation

The tanker was sailing from the Russian Baltic Sea port of Primorsk toward the Suez Canal, bound for Singapore. It was flying the flag of Cameroon, but French authorities said Cameroon had struck the vessel from its registry weeks earlier. According to Paris, the ship was therefore navigating without nationality in violation of international maritime law, giving the French navy the right to board and detain it.

Tuesday, the French navy boarded the Deliver as it transited off the coast of Sicily in violation of the law of the sea.

Defence Minister Catherine Vautrin stated the tanker was suspected of operating under a false flag and called the shadow fleet a direct threat to maritime safety and the environment.

Wider crackdown on shadow fleet

Since the start of 2026, European countries have seized nine tankers suspected of belonging to Moscow's sanctions-evasion network, four of them by France. Another three were inspected under a European naval mission in the Mediterranean, according to a Western military source. The campaign has intensified in recent months, with French and British forces coordinating on several occasions.

Legal and economic context

The shadow fleet consists of often ageing vessels with opaque ownership structures, used to transport oil and gas while bypassing Western price caps and sanctions imposed after the 2022 invasion of Ukraine. Vautrin stressed that cutting off these financing routes is essential to curbing Russia's war economy. The EU is currently negotiating its 21st sanctions package, aimed at closing the loopholes that allow Moscow to continue exporting millions of barrels to countries such as India and China.

We will not allow the shadow fleet to circumvent sanctions and finance Russia's war effort. Europe is determined.

British action and Russian reaction

On 14 June, the UK carried out its first operation of this kind, boarding the tanker Smyrtos in the English Channel. According to the Daily Telegraph, the outgoing government of Keir Starmer is considering confiscating and auctioning the roughly 100,000 tonnes of Urals crude onboard, estimated to be worth around £35 million, with the proceeds going to Ukraine. Moscow considers all such interceptions illegal and is reportedly exploring legal action over the Smyrtos case.
