In a landmark operation, British armed forces successfully intercepted the Russian oil tanker, Smyrtos, in the English Channel. The operation carried out in the early hours of Sunday involved Royal Marine Commandos and officers from the National Crime Agency, marking a first for the UK in leading such actions against the shadow fleet, which is crucial for funding Russia's war in Ukraine, according to Reuters and BBC.

The six-hour operation was supported by air and naval assets, including RAF P-8 surveillance aircraft and several Royal Navy ships. Following the boarding, the vessel was detained and will be monitored off the south coast while investigations continue, as confirmed by the UK Ministry of Defence, according to Al Jazeera and India Times.

Prime Minister Keir Starmer emphasized the operation's significance, stating, "This successful operation delivers yet another blow to Russia," reinforcing the UK's commitment to disrupt resources aiding Putin's illegal war. Starmer's comments came alongside Defense Secretary Dan Jarvis's assertions regarding the ongoing efforts to counteract the "shadow fleet," which helps evade sanctions on Russian oil, according to Le Monde and NPR.

Additionally, this interception has been acknowledged positively by Ukrainian President Volodymyr Zelensky, who expressed gratitude towards the UK for its proactive stance against the shadow fleet. The actions taken by the UK come after months of calls for tougher measures against ships linked to Moscow's oil trade, which reportedly constitutes a significant revenue source for the country, as noted by South China Morning Post.
