Ukrainian long-range drones struck the Gazprom-owned Moscow oil refinery in the early hours of Tuesday, igniting a large fire at a facility that supplies roughly 40 per cent of the capital’s petrol and half its diesel. Moscow Mayor Sergei Sobyanin said air defences intercepted around 60 drones overnight, but at least one hit the refinery in the Kapotny district, just 15 kilometres from the Kremlin. No casualties were reported, yet the attack forced flight restrictions at all four of Moscow’s international airports. President Volodymyr Zelensky confirmed the operation, sharing footage of a drone bursting into a fireball on impact and calling it a “just response” to Russia’s protracted invasion. A fuel depot in the southern Krasnodar region was also set alight, extending the reach of a campaign that has doubled the number of drone strikes on Russian refineries since the start of 2026.

The refinery strike was a direct reprisal for a massive Russian aerial assault on Ukraine the previous day. Moscow launched 70 missiles and more than 600 drones at Kyiv, Kharkiv and Dnipro, killing at least 11 people, including five rescue workers, and wounding dozens. The 11th-century Dormition Cathedral, a UNESCO World Heritage site within the Kyiv Pechersk Lavra monastery complex, suffered significant fire damage. While Kyiv blamed a direct Russian strike, the Kremlin attributed the destruction to a falling Ukrainian Patriot missile. The attack drew international condemnation and overshadowed the opening of the G7 summit in Evian, France, where leaders are expected to press for a ceasefire framework.

Viewed from Moscow, the refinery fire is the latest in a series of embarrassing breaches of the capital’s air defences, now on the ninth consecutive day of drone alerts. The plant processed 11.6 million tonnes of crude last year and is critical to the region’s fuel supply; its disruption, even if temporary, adds to a pattern of partial shutdowns that have depressed Russian petrol, diesel and jet fuel output. From Kyiv, the strike demonstrates a growing ability to hit strategic targets 500 kilometres beyond the front line, using domestically produced long-range systems that Zelensky described as a key component of pressure on the Kremlin. In European capitals, the tit-for-tat escalation complicates diplomatic efforts: the G7 aims to revive negotiations, and the EU has just opened accession talks with Ukraine, yet the cycle of retaliation shows no sign of abating.

Analysts in London note that the war, now longer than the First World War, is increasingly defined by deep-strike warfare against energy infrastructure, with both sides seeking to erode the other’s logistical capacity and domestic morale. The attack on Moscow’s most important oil source, combined with the damage to Kyiv’s sacred heritage, underscores how the conflict is blurring the lines between military and symbolic targets. As G7 leaders convene, the challenge will be to translate battlefield dynamics into a sustainable diplomatic process, even as the range and intensity of strikes continue to grow.
