In brief
In the English Channel, the United Kingdom boarded and seized the MT Smyrtos, a Russian “shadow fleet” tanker, after Moscow’s president threatened retaliation if Western powers continued similar seizures. Royal Marine Commandos conducted the operation, detaining captain Ajay Pant who faces sanctions‑breach charges. The UK maintains the raid complied with maritime law and that its forces operate within that framework, while Russia is accused of using a fleet of over 700 vessels to ferry sanctioned oil. The seizure is part of a broader, escalating effort by the EU and Western nations to clamp down on the shadow fleet that fuels Russia’s war in Ukraine. Several EU member states have boarded or detained vessels suspected of evading sanctions, and Italy recently seized a tanker over flag‑misuse allegations. The incident underscores the geopolitical tension over oil traffic controls and the legal justification adopted by Britain against Russian allegations of piracy.
The United Kingdom has defended a High Court operation that saw a Russian "shadow fleet" tanker, the MT Smyrtos, seized in the English Channel after the Kremlin’s president promised to respond in kind to further seizures.
The chartered vessel, docked off Weymouth, was boarded by Royal Marine Commandos in a first‑of‑its‑kind raid that allegedly disrupted the sanctioned tanker in June. Royal Marines seized the ship and detained its captain, Ajay Pant, who has been charged with breaching Russian sanctions by allowing the delivery of Russian oil.
Putin, while on a Pacific‑fleet drill, criticised the UK and other Western nations for "seizing our vessels" and said Russia would retaliate wherever it deemed necessary. The Ministry of Defence emphasised that the operation was fully compliant with international maritime law and that UK forces operate within that framework.
Russia is believed to run a shadow fleet of more than 700 vessels carrying roughly 75% of sanctioned oil – a lifeline for Vladimir Putin’s war in Ukraine. The EU has over 630 sanctioned vessels, banning them from EU ports and detaining suspected tankers in various theatres, including the Mediterranean, where the Italian navy boarded a tanker on suspicion of false flagging.
Other Western countries have seized or detained Russian‑linked vessels or carried out boardings when sanctions violations were suspected, so the UK’s seizure is part of a wider effort to curb Russia’s illicit oil traffic.
