MOSCOW — A Ukrainian drone barrage that Russian officials described as the largest of the year set fire to Moscow's biggest oil refinery over the weekend, halting fuel processing at a plant that supplies roughly 40 percent of the capital's gasoline and jet fuel just as the country wrapped up three days of parliamentary voting.
Russia's Defense Ministry said it shot down 1,110 Ukrainian drones overnight across 19 regions and occupied Crimea, the largest single-night total reported so far in 2026, eclipsing a previous high of 822 in August, according to wire reporting on the attack. Moscow Mayor Sergei Sobyanin called the raid unprecedented and suggested it was timed deliberately, saying it appeared "planned with the aim of disrupting the elections."
Refinery Knocked Offline for Weeks
Multiple drones struck the Gazprom Neft-owned Moscow Oil Refinery in the Kapotnya district, roughly 25 kilometers from the Kremlin, damaging the plant's primary crude distillation unit, its integrated processing unit and an isomerization unit, Ukraine's General Staff said. Large fires broke out across the 245,000-barrel-a-day facility, and Russian energy officials told Reuters that both of the refinery's crude distillation units had halted operations entirely, with repairs expected to take several weeks. Regional governor Andrey Vorobyev said two people were killed and 20 injured by falling drone debris across the greater Moscow region.
Ukrainian President Volodymyr Zelenskyy said the strikes had "very significant impact," a rare moment of Ukrainian officials publicly claiming credit for the scale of damage rather than staying silent, as is more typical after attacks deep inside Russian territory.
A War Still Escalating in Its Fourth Year
The attack lands amid a broader pattern of intensifying long-range strikes on both sides as Russia's full-scale invasion of Ukraine, now in its fourth year, shows no sign of a negotiated end. Ukraine has increasingly targeted Russia's oil infrastructure — refineries, pipelines and export terminals — arguing that degrading Moscow's energy revenue is one of the few levers it has to pressure the Kremlin, while Russia has continued its own strikes on Ukrainian power and gas infrastructure ahead of another winter.
The refinery's shutdown is unlikely to trigger immediate shortages in Moscow given the country's broader refining capacity, but it adds to a string of attacks this year on facilities supplying the capital region, and analysts expect Ukraine to continue targeting energy infrastructure as autumn deepens. Russian officials have not said whether the parliamentary election results, in which turnout topped 47 percent by midday Sunday, will affect the Kremlin's approach to the war going forward.
