UK armed forces board Russian shadow fleet oil tanker in English Channel, PM says

British Royal Marine Commandos and law enforcement officers successfully intercepted a Russian 'shadow fleet' oil tanker in the English Channel during a six-hour operation on Sunday, June 14, 2026. The vessel, identified as the SMYRTOS, was boarded by specially trained personnel from the Royal Marines and the National Crime Agency in what Prime Minister Keir Starmer described as the first UK-led mission of its kind.

This intervention was aimed at disrupting Russia's capacity to finance its ongoing conflict in Ukraine by bypassing international sanctions. The tanker is now being held and monitored off England's south coast as investigations proceed. British officials emphasized that the operation was conducted in accordance with both domestic and international law and was coordinated with France, reflecting a broader effort to reduce Russia's oil revenues.
