A Ukrainian drone sparked a fire and damaged a facility at Moscow region's largest refinery on Tuesday and oil producer Tatneft announced nationwide fuel purchase ‌caps, signs of the widening impact of Kyiv's campaign to target Russian ​energy infrastructure.

Seeking to hit a key source of Russia's war funds, Ukraine's attacks on refineries have doubled since the start of 2026, leading ⁠to full or partial shutdowns of oil processing and a decline in gasoline, ​diesel, and jet fuel output, according to official data, social media, and Reuters calculations.

Ukrainian ⁠President Volodymyr Zelenskyy said the Gazprom Neft refinery was hit from a distance of 500 km (311 miles), illustrating the reach of Ukraine's long-range strikes.

"This is a just response to Russian strikes – and to the dragging ‌out of a war that must be ended," he said on ​X.

Local emergency services ‌said a fire at the refinery had been put out and had not affected operations. Earlier, Moscow Mayor Sergei Sobyanin ‌said a facility at the site had been damaged, without giving further details.

The plant, which has been targeted multiple times, processed 11.6 million tons of oil in ⁠2024, producing 2.9 million tons of petrol ‌and 3.2 million tons ⁠of diesel, according to the latest available data.

Gazprom Neft did not immediately respond to a request for comment.

Around ⁠a dozen ⁠Russian regions have seen some fuel supply disruptions in recent weeks, but central authorities have so far described issues ‌as localized bottlenecks.

Recent long lines for gasoline in Russian-controlled Crimea and the southern Krasnodar region underscore the sensitive domestic fallout from Ukraine's strikes.

On Tuesday, oil producer Tatneft said it was ‌introducing restrictions on ​fuel purchases at its ‌hundreds of stations across Russia, the first retailer to implement nationwide caps.

A Tatneft station in Serpukhov district, south of Moscow, was limiting sales to 20 ​liters of gasoline per car or 40 liters of diesel and accepting only cash, according to a Reuters witness.
