In brief
The United Kingdom boarded the Russian tanker Smyrtos in the English Channel, citing violations of international sanctions and its role in fueling the war in Ukraine. Russia’s President accused Western nations of piracy and warned of responses “in kind.” Western authorities allege that Russia’s vast, covert “shadow fleet” of over 700 vessels evades sanctions through opaque ownership. The UK maintains its actions followed international law, contrasting its own compliant operations with the alleged Russian strategy. The incident adds to a broader EU crackdown on shadow fleet vessels, with more than 630 ships now sanctioned.
The UK government has defended its seizure of a Russian “shadow fleet” oil tanker in the English Channel, following a warning from President Vladimir Putin that the West would “respond in kind.”
The tanker, named Smyrtos, was anchored offshore of Weymouth after Royal Marines Commandos boarded it June 15, in the first operation of its kind to disrupt a sanctioned vessel. The ship’s captain, Ajay Pant, faces charges of breaching Russian sanctions by allegedly supplying or delivering prohibited Russian oil.
Overseeing Russian navy drills in the Pacific, Putin blasted Western seizing of “our vessels” as piracy, promising retaliation wherever the West Next such action occurred. He warned that such moves would be met “anywhere” that the Kremlin could target.
Western nations, however, insist Moscow operates a shadow fleet of hundreds of vessels designed to dodge sanctions imposed on its oil exports. These ships allegedly resort to intricate ownership layers and other tactics to conceal their cargo’s link to Russia.
The Ministry of Defence estimates the Russian shadow fleet totals more than 700 vessels, responsible for roughly 75 % of sanctioned Russian oil – a “critical lifeline” that fuels the Kremlin’s illegal war in Ukraine.
The UK’s spokesperson said that its armed forces and law‑enforcement boarded the Smyrtos “in full accordance with international law,” stressing that UK commercial vessels operate firmly under maritime law, in contrast to the alleged shadow fleet.
The tanker remains detained near Weymouth, monitored by British authorities, whilst the ship’s owner manages the vessel’s upkeep. Twenty‑two of the original 25 crew have been repatriated.
Putin’s threat comes as the EU intensifies pressure on the shadow fleet. In August 2026, the EU has sanctioned more than 630 individual vessels, limiting their access to EU ports, and several European navies have boarded or detained suspected rigs.
