Ukraine Torches Russia’s “Untouchable” Fuel Reserve, UK Seizes Shadow Fleet Tanker in Joint Blitz
Ukraine’s military drones set fire to Russia’s strategic fuel reserve and hit an explosives-linked chemical plant in a single night, while British commandos boarded a sanctioned Russian oil tanker in the English Channel, marking a coordinated escalation to cut off Moscow’s war supplies and revenue.
Ukraine launched a major escalation overnight, striking two strategic targets deep inside Russia. A massive fire erupted at the Kombinat Temp fuel depot in Rybinsk, which belongs to Rosrezerv—the state agency that hoards fuel reserves for national emergencies [172750]. These reserves are normally considered untouchable. The same night, a separate drone attack hit a chemical plant in Tula Oblast that is linked to explosives production [172750]. Ukrainian officials confirmed the strikes, saying they aim to cut off fuel and material supplies for Russia’s war effort [172750].
The attack on the fuel reserve comes as Russia’s gasoline crisis spreads. The Russian Energy Ministry created a task force on 8 June to manage a growing shortage, blaming “enemy air attacks,” but the crisis has spread from 15 to 25 regions in just five days, now also affecting six areas in occupied Ukraine [170577]. Meanwhile, all three refineries in Rosneft’s Samara region are now offline or running at reduced capacity after a drone strike halted operations at the Kuibyshevsky plant on 10 June, damaging its two main processing units [170576]. The Kuibyshev refinery had already suspended operations after a previous drone attack in August 2025 and was hit again in January 2026 [169831].
In a separate but related operation, British armed forces boarded a sanctioned Russian oil tanker in the English Channel on Sunday, in the first operation of its kind to disrupt the revenue funding Moscow’s war in Ukraine [172634]. Commandos from the Royal Marines, alongside officers from the National Crime Agency (NCA), stormed the vessel *Smyrtos* in the early hours [172634]. The ship, which sails under the flag of Cameroon, is part of what experts call Russia’s “shadow fleet”—aging tankers used to evade Western sanctions and export oil illegally [172634]. The operation involved Chinook helicopters, other aircraft, a frigate, and a minehunter [172634]. A statement from the UK Ministry of Defence confirmed the boarding was “successful,” and Ukrainian President Volodymyr Zelensky expressed gratitude, calling it a vital step in cutting off the financial resources that fuel Russia’s invasion [172634].
