EU's Irini mission boards shadow-fleet tanker MV Midag, which sailed under false flag

The boarding at sea

On Friday, 13 November, forces from the EU's Irini operation boarded the tanker MV Midag in the central Mediterranean. The mission published the news on X, and Kaja Kallas, the EU's high representative for foreign affairs, reposted it and said the boarding confirmed the ship was sailing under a false flag. The procedure rests on Article 110 of the UN Convention on the Law of the Sea, which lets warships in international waters check a vessel suspected of lacking a valid nationality or of flying its flag irregularly. Il Messaggero reported that two warships carried out the boarding with help from an Italian helicopter. Rzeczpospolita said the Italian vessel Thaon di Revel and a Greek unit took part, alongside a Polish patrol aircraft. Kallas said the ship probably belongs to Russia's shadow fleet.

Flag and ship details

The tanker was reportedly sailing from Benin to Istanbul under the flag of Cameroon, and Rzeczpospolita reported that it was subject to EU sanctions. According to the same report, the Cameroonian flag turned out to be false. Maritime databases, as cited by Il Messaggero, list the vessel under the flag of Zimbabwe, put its length at about 241 metres and its gross tonnage at more than 106,000 tonnes. Moscow has not confirmed the identity of the vessel, Rzeczpospolita reported.

Sanctions and earlier boardings

Kallas said EU foreign ministers would approve new sanctions lists on Monday, 16 November. The lists are aimed at banks, buyers and companies that support the shadow fleet. Irini forces had already checked the tanker MV Sun in late August, and an inspection of the MV Toa Payoh took place earlier in August. Rzeczpospolita described the Sun case as the sixth ship the EU forces had checked in the preceding months for possible links to the shadow fleet. In the summer of 2026, Kallas had announced that EU countries were allowed to stop foreign tankers in the Mediterranean for inspection, and the EU has since widened the powers of its ships to inspect vessels it links to the fleet.

The mandate of Irini

Irini was launched in March 2020 to enforce the UN arms embargo on Libya during the second Libyan civil war. Its original mandate covered countering illegal arms trafficking, gathering information on oil smuggling and contributing to the fight against human trafficking. It also supported the training of Libyan law enforcement institutions and search and rescue operations. A newer task is to limit the activity of Russia's shadow fleet, and the Mediterranean is described as a key transit and transfer zone for ships Moscow uses to avoid Western sanctions.

Russian reaction

Russia's foreign ministry has complained about EU abuses in the Irini operation, according to RBK as cited by Rzeczpospolita. Moscow says the mission has become a tool for intimidating commercial carriers and restricting freedom of navigation. It argues that Brussels is breaching freedoms set out in the 1982 UN Convention on the Law of the Sea. Vladimir Putin warned that Russia would take retaliatory action against those who threaten Russian ships.

What comes next

Foreign ministers are due to vote on the new sanctions lists on Monday, 16 November. Kallas said the EU would keep disrupting the shadow fleet both at sea and through diplomatic channels. The identity of the boarded ship remains unconfirmed by Moscow, and the Russian response will be watched in the days after the sanctions vote.
