On Sunday, September 20, 2026, Ukraine launched one of its biggest drone strikes on Moscow during the final hours of Russia’s parliamentary elections, igniting a major oil refinery and intensifying a campaign that has severely disrupted Russia’s domestic fuel supplies and refining capacity.
Moscow Refinery Hit in Massive Drone Attack as Russian Elections Close
The Sunday assault on the Russian capital sent vast plumes of smoke into the air from a burning facility, with Moscow mayor Sergei Sobyanin reporting that over 450 drones were shot down in the most massive
attack seen since the war began over four years ago. The strike coincided precisely with the close of polling in Russia’s parliamentary elections.
The campaign against energy infrastructure has escalated sharply over the past 18 months. The few facilities that remain untouched sit deep out of range in eastern Siberia and the far east, between 3,500km and 6,500km from the Ukrainian border.
This sustained strategy has driven fuel throughput down to its lowest level in more than 20 years by June, marking a 30 per cent blow compared to a year earlier. Gasoline output dropped by 20 per cent relative to 2024 figures, while diesel production fell by nearly 30 per cent.
Severe Fuel Shortages and Rationing Across Russian Regions
The refinery disruptions have triggered widespread fuel shortages across 92 per cent of Russia’s regions, prompting roughly two-thirds of them to introduce rationing measures. Motorists have faced grueling waits of up to 40 hours at filling stations, accompanied by rising oil and gas prices that have forced the Russian government to restrict oil exports to protect domestic supplies.
Half of Russia’s six largest diesel-producing refineries either cut or completely halted output in September following strikes, as reported by Reuters. Among them, the Kirishi refinery in Leningrad Oblast shut down entirely, while the NORSI plant in Nizhny Novgorod and the Volgograd refinery operated at only about a fourth of their capacity.
In Leningrad Oblast, regional authorities implemented temporary fuel limits at gas stations. Governor Alexander Drozdenko confirmed that the measures were temporary and scheduled to remain in effect until Oct. 1, noting that the situation on the ground remains difficult.
Targeting Specific Refinery Units to Maximize Disruption
Ukraine’s tactical approach has evolved to bypass passive defenses. As the International Energy Association observed, Ukraine is increasingly using multiple waves of drones against individual refineries, seeking to overwhelm protective netting and other largely passive drone defence measures.
Long-range capabilities advanced rapidly during the first half of 2026, enabling a strike on July 7 against Gazprom Neft’s Omsk refinery in Siberia—Russia’s largest facility, situated roughly 2,500 kilometres from the Ukrainian border and capable of processing 450 thousand barrels per day.
“Its long-range capabilities and targeting have also advanced rapidly, particularly during the first half of 2026. This expanded reach enabled the 7 July strike on Gazprom Neft’s 450 thousand barrels per day (kb/d) Omsk refinery, Russia’s largest, roughly 2,500 kilometres from the Ukrainian border.”

While primary processing units like crude distillation units can generally be repaired within a week or two, secondary units take significantly longer. Damages to complex secondary facilities—such as fluid catalytic crackers, hydrocrackers, reformers, and hydrotreaters—require an average of six to eight months to fix. To cope with the resulting deficits, Russia has permitted the production of lower-quality energy, including higher-sulphur grades of gasoline for the first time since 2016.
Economic Toll and International Repercussions Amid Trump’s Demands
Assessments of the financial damage vary across international observers.
At the same time, broader market dynamics complicate the picture.
The disruption has drawn sharp reactions from Washington. US President Donald Trump publicly urged Ukrainian leadership to halt attacks on Russian diesel infrastructure, claiming those strikes were driving a global spike in fuel prices. However, market evidence points to the U.S.-Israeli war against Iran and the Strait of Hormuz closure as the primary drivers of the worldwide diesel price surge.
