British commandos have intercepted a sanctioned Russian shadow fleet oil tanker in the English Channel, leading for the first time an operation to disrupt the oil revenue that helps fund Russia's war in Ukraine.
The vessel Smyrtos was sailing under a Cameroonian flag.
Royal Marine Commandos and National Crime Agency (NCA) officials boarded it in the early hours on Sunday, with support from Chinook helicopters and other aircraft, a frigate and a minehunter.
