Britain confiscates the MT Smyrtos in the Channel after a Royal Marines boarding, a move defended as legal amid Russian threats to respond in kind.

The UK arrested the Russian tanker MT Smyrtos anchored off Weymouth, a vessel linked to a shadow fleet that circumvents sanctions. The seizure came after President Vladimir Putin threatened to retaliate, calling such actions piracy. British officials say the operation complied with international law and aimed to curb Russia’s illicit oil revenue. EU sanctions now target over 630 vessels. The ship remains held by UK authorities while the crew has largely been repatriated.

UK Seizes Russian Shadow Fleet Tanker Amid Putin Threats

Britain confiscated the Russian-owned tanker MT Smyrtos anchored off the south coast of England in a first‑of‑its‑kind naval operation.

Royal Marines commandos boarded the vessel in June in an effort to block a so‑called “shadow fleet” that Russia uses to sidestep EU sanctions on its oil exports. The captain, Ajay Pant, is now charged with breaching sanctions by shipping prohibited Russian oil.

In a video statement, President Vladimir Putin warned that “the West will have to respond in kind” if it continues to seize Russian tankers. He dismissed the UK’s move as piracy, calling the seized vessels “banditry.” The UK Ministry of Defence said the boarding was carried out in full compliance with international law and aimed to protect global trade and security.

The UK says Russia operates a fleet of more than 700 vessels that carry roughly 75% of the country’s sanctioned oil. The “shadow fleet” is described as a critical lifeline for the Kremlin’s war effort in Ukraine.

The EU, in response, has sanctioned over 630 shadow‑fleet vessels as of mid‑August 2026, banning them from the bloc’s ports. Many Western states have seized or boarded suspected vessels in recent months, including an Italian navy operation in the Mediterranean.

The MT Smyrtos remains detained by the Department of Transport near Weymouth, while the bulk of the crew has been repatriated. The British authorities continue to monitor the vessel as the geopolitical standoff unfolds.
