European Union naval forces boarded a ship suspected of being part of a secret Russian fleet in the Mediterranean Sea on November 13, EU foreign policy chief Kaja Kallas announced today.
"The operation is part of the EU's efforts to target the Russian secret fleet - the network of ships that Moscow uses to transport oil while avoiding Western sanctions. The crude oil tanker MV MIDAG was sailing under a false flag and was intercepted by the EU's Operation IRINI," Kallas writes in X.
Operation IRINI is the EU mission that monitors arms and oil trafficking in the Mediterranean and according to the ship tracking website MarineTraffic, the ship was sailing under the Zimbabwean flag.
"The EU will continue to strike at the Russian secret fleet at sea and through diplomatic means," Kallas declared.
The action was carried out under Article 110 of the United Nations Convention on the Law of the Sea, which allows for the inspection of ships in certain circumstances.
On November 16, EU foreign ministers are expected to adopt new sanctions lists against Russia, including banks, buyers and companies supporting the secret fleet, Kallas announced.
The EU has stepped up action against vessels suspected of being part of this network. In August, EU forces boarded another suspected tanker, the MV Sun, also in the Mediterranean, to verify its flag.
Russia's secret fleet has contributed significantly to the Kremlin's ability to finance the war against Ukraine. As of May 2026, the Ukrainian government registry had identified 1,404 ships as part of this fleet.
