Several NATO-produced magnetic mines had been detected on a tanker in Russia’s Baltic Sea port of Ust-Luga, according to Russia’s Investigative Committee. The committee said the mines were found by divers during an inspection of the hull of the tanker Arrhenius, which arrived from Belgium’s port of Antwerp to load liquefied petroleum gas. This discovery raises concerns about the security of shipping lanes in the region.
The incident is part of a broader trend of suspected sabotage aimed at undermining Russia's energy infrastructure. Last year, Russia ordered divers to inspect ships in its ports after four oil tankers were targeted. The Suezmax tanker Koala ran aground at Ust-Luga after a blast in its engine room in February 2025. This increased vigilance has led to the detection of several suspicious items on vessels entering Russian ports.
The Arrhenius, which is Liberia-registered and managed by Maple Mariner Holding in the UAE, was scheduled to sail to the Turkish port of Samsun. However, its arrival at Ust-Luga was delayed due to the discovery of the magnetic mines. The vessel's safety has been ensured through the deactivation of the mines.
A spokesperson for Russia’s Investigative Committee, Svetlana Petrenko, confirmed that the mines were produced by a NATO country. She stated that the vessel entered Ust-Luga on May 20 and was initially scheduled to depart for Samsun. The committee's investigation has concluded that the magnetic mines could not have been installed in Russia’s territorial waters.
The lack of evidence suggests that the mines may have originated from a foreign ship or cargo. This raises questions about the effectiveness of international cooperation in preventing such incidents. NATO was not immediately available for comment, highlighting the need for greater transparency and collaboration between nations.
The detection of magnetic mines on a tanker is a serious security concern. It highlights the ongoing threat of terrorism and sabotage in Russia's ports. The incident underscores the importance of enhanced safety measures and increased vigilance in preventing such incidents.
Russia has taken steps to boost its port security following several suspected acts of sabotage. The measures have included increased inspections and divers' checks on vessels entering Russian ports. This increased scrutiny has led to the detection of suspicious items on ships, including the magnetic mines found on the Arrhenius.
The incident serves as a reminder of the importance of maritime security and cooperation between nations. It highlights the need for greater collaboration and information-sharing to prevent such incidents in the future.
Authorities have ensured the safety of the vessel by deactivating the magnetic mines. The incident is being closely monitored, and further investigations are underway to determine the origin and purpose of the mines.
