British forces have intercepted and boarded a Russian-linked oil tanker in the English Channel during a major military operation aimed at enforcing sanctions against Russia’s oil trade.
The operation, carried out in the early hours of Sunday, involved Royal Marine Commandos, officers from the National Crime Agency (NCA), and support from the Royal Air Force. Authorities said the vessel, identified as Smyrtos, is now being held off the southern coast of England while investigations continue.
According to officials, the tanker had a crew of 25 on board. Video footage released by the Ministry of Defence showed commandos descending from a helicopter onto the ship before conducting security searches and inspecting documents.
Prime Minister Keir Starmer described the mission as a significant step in efforts to disrupt Russia’s ability to finance its war in Ukraine.
The vessel is believed to be part of Russia’s so-called “shadow fleet” — a network of tankers used to transport oil while circumventing international sanctions. British authorities say these vessels play a major role in maintaining Russian oil exports despite restrictions imposed by Western nations.
Tracking data indicates that Smyrtos, sailing under a Cameroon flag, departed from Russia’s Ust-Luga oil terminal near St. Petersburg earlier this month before entering the English Channel. The tanker had previously been sanctioned and reportedly changed both its name and flag registration after restrictions were imposed.
The UK government said the boarding took place in international waters and complied fully with international law. Officials noted that the operation followed weeks of planning and coordination with allied countries, including France.
The move forms part of broader efforts by the UK and its partners to target Russia’s oil revenues and reduce funding available for Moscow’s military operations in Ukraine.
Ukrainian President Volodymyr Zelensky welcomed the action, calling for stronger measures against vessels involved in transporting sanctioned Russian oil.
The operation also comes amid ongoing debate within Britain over defence spending and military readiness, following recent resignations of senior government officials who argued that greater investment in defence is needed to address emerging security challenges.
