EU Naval Force Boards Suspected Russian Shadow Fleet Tanker Sailing Under a False Flag in the Mediterranean

Economic Warfare & Trade Policy › Sanctions

European Union naval forces boarded a suspected Russian shadow fleet tanker, the MV Midag, in the Mediterranean Sea on Friday, Nov. 13, and confirmed it was sailing under a false flag, EU foreign policy chief Kaja Kallas said on Sunday, Nov. 15, a day before EU foreign ministers are due to approve new Russia sanctions aimed at the fleet’s backers.^[1][2]

What we know about the boarding

Troops from EUNAVFOR MED Irini, the EU naval mission that monitors arms and oil trafficking in the Mediterranean, carried out the boarding. Kallas announced it in a post on X on Sunday, with a photo of the operation.^[1][2]

The Midag is a crude oil tanker. The boarding was conducted under Article 110 of the United Nations Convention on the Law of the Sea, which permits the inspection of ships in certain circumstances. Irini uses it for what it calls flag verification boardings.^[1][3] Ship-tracking site MarineTraffic listed the vessel as sailing under the flag of Zimbabwe, the Kyiv Independent reported.^[1]

“The EU will keep disrupting Russia’s shadow fleet at sea and through diplomatic means,” Kallas wrote.^[1]

New sanctions due Monday

Kallas said EU foreign ministers are set on Monday, Nov. 16, to approve new Russia sanctions listings targeting banks, buyers and companies that support the shadow fleet.^[1][2]

Russia uses the shadow fleet to move oil past Western sanctions, relying on complex ownership structures, flags of convenience and other tactics that hide where cargoes come from.^[2] As of May 2026, a Ukrainian government register had identified 1,404 vessels as part of the fleet, the Kyiv Independent reported.^[1] For the wider pressure on Moscow’s oil revenue, see our Ukraine War Charts.

A Libya mission with a new job

Operation Irini was launched in March 2020 to enforce the U.N. arms embargo on Libya during the country’s civil war.^[2] The Council of the European Union has since renewed its mandate until March 31, 2029, and added three tasks: helping to constrain Russia’s shadow fleet, strengthening maritime domain awareness and supporting the protection of critical maritime infrastructure.^[3]

The mission describes the Mediterranean as a key transit and transfer area for the fleet, linking Russian oil exports to world markets, and says such boardings let it help constrain the fleet where applicable.^[3]

The Midag is not the first such case. In August, Irini forces boarded the tanker MV Sun to verify its flag, and Euronews reported a separate mission targeting the MV Toa Payoh.^[1][2] Europe’s navies have been active in northern waters too: Finland confirmed a strike on a Russian warship in the Gulf of Finland this week.

Drone strikes on ships off Romania

The boarding came as Romania reported drone strikes on commercial shipping off its Black Sea coast near the Sulina canal, a route linking the Danube to the sea that Ukraine uses for exports.^[4][5]

Accounts of the number of ships differ. The Kyiv Independent reported three vessels hit over two days: the Palau-flagged Larissa 1 on Nov. 13, then the Greek-flagged tanker Evia Petrol V and the bulk carrier Marsol on the evening of Nov. 14, citing Romanian authorities and media.^[4] Euronews reported three ships struck on Saturday, Nov. 14, naming the Evia Petrol V, the Marsol and the oil products tanker Ali Najafov, in addition to the Larissa 1 the day before.^[5] Crews put out fires on board and no casualties were reported.^[4][5]

Romanian authorities have not established where the drones came from, and Romania sent F-16 fighter jets after radars detected aerial targets in the area.^[4][5] Prime Minister Luca Niculescu called the attacks unacceptable and a violation of international law, Euronews reported. Russia denied targeting countries that neighbor Ukraine.^[5] Earlier: drones crossed into Romania in late October.

What happens next

EU foreign ministers meet on Monday to approve the new shadow fleet listings.^[1] Romanian Defense Minister Ștefan-Radu Oprea is due in Brussels next week, where Black Sea security is expected to be discussed, and has asked allies for surveillance aircraft patrols and counter-drone equipment.^[5] The moves come as Europe moves to join the U.S.-brokered Ukraine peace talks.
