The UK has defended its seizure of a Russian “shadow fleet” oil tanker in the English Channel after President Vladimir Putin warned that the West would be forced to “respond in kind.” The tanker, named MT Smyrtos, was anchored off Weymouth when Royal Marines Commandos intercepted it in a unprecedented operation designed to block sanctioned Russian oil flows.
The vessel’s captain, Ajay Pant, has been charged with breaching Russian sanctions for allegedly supplying or delivering prohibited oil to the Kremlin. Russian officials have condemned this raid as an act of piracy and banditry, accusing the UK and its allies of violating maritime law.
Western states maintain that Russia runs a covert fleet—hundreds of vessels that evade sanctions by using complex ownership structures—responsible for 75 percent of sanctioned Russian oil exports. The UK Ministry of Defence says that this fleet is a “critical lifeline” for the Kremlin’s war in Ukraine.
Meanwhile, Putin warned that any further seizures would be met with retaliation, not necessarily in the same waters, but “whenever we deem it necessary and appropriate, anywhere.” Russian Navy Pacific Fleet commander Viktor Liina added that Western countries might be operating their own shadow fleets, setting up a cautious stance on future maritime raids.
The UK government insists that the boarding operation was conducted “in full accordance with international law” and that it aims to disrupt and deter the shadow fleet’s harmful activities. UK forces and commercial vessels, the spokesperson noted, operate “firmly in line with international maritime law.”
Despite the UK’s legal approach, the incident remains part of a larger EU effort that began sanctioning individual shadow fleet vessels in 2024. As of mid‑August 2026, more than 630 vessels are sanctioned and barred from EU ports.
Russian sailors “theftS aid” are also a target. In July, 22 of the 25 crew members aboard the Smyrtos were repatriated by the UK transport authorities. The vessel is now held near Weymouth under tight monitoring, and the ship’s owner is responsible for crew supplies.
The incident underscores the intensified pressure from EU nations, with spokesperson Anitta Hipper declaring that “rules of international law cannot be ignored by any state.” Russia’s shadow fleet continues to be a key vector for circumventing sanctions and financing its military ambitions.
