Magnetic Mines Found on LPG Carrier in Ust-Luga Port Raise Security Concerns

Russian authorities reported the discovery of two magnetic mines attached to the hull of the LPG carrier Arrhenius, which arrived at Ust-Luga from Belgium on May 20, 2026. The Federal Security Service (FSB) stated that the mines, each containing 7 kg of explosives, were likely manufactured in a NATO country. The ship had previously anchored offshore in Antwerp due to a strike by Belgian port workers. Russian officials assert that the mines could not have been attached while in Russian waters. An investigation is underway to identify those responsible for the attempted attack. The incident has heightened security measures at Russian ports, following previous attacks on energy infrastructure. The crew of the Arrhenius was evacuated but later allowed to return to the vessel, which remains in the vicinity of Ust-Luga.
