For the first time, the Swedish Navy has acknowledged that Russia's so-called "shadow fleet" in the Baltic Sea may conduct espionage operations, as reported by SVT.

The Russian "shadow fleet" transports huge volumes of petroleum products daily across the Baltic Sea.

Ewa Skooh Haslum, the head of the Swedish Navy, believes that some ships could be used for espionage, including intercepting communications.

Haslum noted that antennas and masts not typical of fishing vessels have been detected, indicating other purposes related to the activities of these ships.

Measures to stop such activities were discussed at an EU meeting in Luxembourg. Tobias Billström, Sweden's Minister of Foreign Affairs, noted that the "shadow fleet" had become a serious problem.
