Ukraine struck oil refineries in Russia's Krasnodar and Yaroslavl regions on June 28, 2026, President Volodymyr Zelenskiy confirmed, extending a drone campaign against Russian energy infrastructure that has already put one major facility out of commission for the remainder of the year.

The two overnight strikes add to a string of attacks that have systematically targeted the downstream end of Russia's oil sector. Earlier in June, Ukraine hit Moscow's Kapotnya refinery twice — on June 16 and again on June 18 — according to Reuters. The cumulative damage from those strikes was severe enough that Kapotnya is unlikely to resume production before 2027, leaving it offline for at least six months, Reuters reported on June 24.

Krasnodar and Yaroslavl are not peripheral targets. The Krasnodar region hosts refining capacity that feeds both domestic consumption and Black Sea export routes. Yaroslavl's Slavneft-YANOS refinery is one of Russia's largest and most complex, processing a wide slate of crude into high-value products. Knocking either facility offline — even temporarily — tightens Russia's ability to supply its own military logistics chain, which runs on diesel and jet fuel, and constrains the export volumes that fund the war effort.

Ukraine's targeting logic follows a clear throughline: refineries are harder to replace than pipelines or storage tanks, require specialized equipment with long lead times, and their loss cascades across both military supply and hard-currency earnings. Russia's ability to source Western refining components has been sharply curtailed by sanctions since 2022, meaning repairs to badly damaged units take months longer than they would have pre-war.

The Yaroslavl strike is geographically notable. Located roughly 250 kilometres northeast of Moscow, YANOS sits well inside Russia's air-defense perimeter — or what that perimeter was assumed to be. Reaching it with enough payload to cause operational damage points to continued evolution in Ukraine's long-range drone capability, whether through improved navigation, saturation tactics, or both.

Russia has not officially confirmed damage at either site as of June 28, which is consistent with its standard posture of downplaying infrastructure strikes. Independent damage assessments typically emerge through satellite imagery within 24 to 72 hours.

The broader context here is one of deliberate strategic attrition. Ukraine cannot match Russia in artillery shell production or manpower, so it has invested heavily in asymmetric tools — long-range drones chief among them — that impose costs disproportionate to their price. Refinery attacks fit that calculus precisely: a drone that costs tens of thousands of dollars can cause damage requiring hundreds of millions to repair and months to restore. With Kapotnya already off the grid and two more facilities now struck, Russian energy planners face compounding pressure across their refining network at a moment when the state budget remains heavily dependent on hydrocarbon revenues.
