**Deck**: Ukrainian forces hit multiple oil and gas facilities deep inside Russia, including a major refinery in Yaroslavl and plants in Krasnodar’s Slavyansk-on-Kuban, in one of Kyiv’s broadest energy strikes to date. The attacks push the war further into Russia’s rear, raising costs for its military logistics and injecting new uncertainty into refined products supply.

Ukraine has carried the war deeper into Russia’s energy heartland, striking at least two major refining and processing complexes that help feed the Kremlin’s military machine and occupied territories. The overnight attacks mark a continuation of Kyiv’s strategy of targeting fuel infrastructure far from the front lines to strain Russia’s war economy and logistics.

Ukrainian Defense Forces say they hit the Slavyansk EKO refinery in Slavyansk‑on‑Kuban in Russia’s southern Krasnodar region overnight, describing the plant as processing up to 5.2 million tons of crude per year and supplying fuel to Russia’s army and occupied Crimea. Footage and local reports showed heavy smoke spreading across the city, with plumes visible up to around 45 kilometers away from the site. Russia’s Ministry of Defense, for its part, said air defenses had shot down 213 Ukrainian drones over multiple regions as well as over the Black and Azov Seas, and acknowledged that a fire broke out at the Slavyansk oil refinery after the attacks.

Satellite‑based fire detection from NASA’s FIRMS system indicated another blaze at the Slavyanskaya oil stabilization and gas processing unit operated by RN‑Krasnodarneftegaz, suggesting that more than one energy facility in the Slavyansk‑on‑Kuban area was hit in the same wave of strikes. While detailed damage assessments remain unclear, the clustering of fires points to a coordinated effort to disrupt a local hub of oil and gas infrastructure that serves both civilian and military demand.

Further north, the Slavneft‑YANOS refinery in Yaroslavl — one of Russia’s largest, with an annual processing capacity of around 15 million tons — was also targeted by Ukrainian drones, according to reporting from the incident. The facility is described as strategically important to Russia’s fuel industry, meaning any sustained disruption could affect supplies across multiple regions and potentially for export. Russian officials have yet to provide a full public account of the extent of damage at YANOS.

For Russian civilians in industrial towns like Slavyansk‑on‑Kuban and Yaroslavl, the immediate risk comes from fires, explosions, and air‑defense interceptions over populated areas. In Krasnodar region, local authorities reported that one person was killed and another injured in overnight incidents involving drones, though they did not specify whether the casualties were directly tied to the refinery strikes. Residents also face the prospect of fuel shortages or price spikes if key facilities are taken offline for repairs.

On the Ukrainian side, the operations are presented as a way to push the cost of war back onto Russia’s rear and to constrain the fuel that powers its armor, artillery, and logistics — particularly for forces in occupied Ukrainian territories and in Crimea, which relies heavily on supplies routed through southern Russia. Each refinery damaged or forced to curtail operations complicates Moscow’s effort to maintain both domestic supply and export revenue at a time when sanctions have already narrowed its options.

For global markets, the impact of individual strikes on Russian refineries may be muted in the short term, but the pattern matters. Russia remains a significant exporter of diesel and other refined products; a sustained campaign against its refining sector creates uncertainty not only over volumes but over the cost of insuring and operating facilities under persistent drone threat. Traders, insurers, and neighboring states will be watching to see whether these hits become a regular feature of the conflict or remain sporadic.

The attacks also expose an awkward reality for Russia’s air defense posture: despite intercept claims in the hundreds, small Ukrainian drones continue to penetrate deep into Russian territory and hit high‑value, fixed infrastructure. Defending an extensive, dispersed network of refineries, depots, and processing plants against swarms of low‑cost UAVs is a resource‑intensive challenge even for a large military.

The next indicators to watch are how quickly Slavyansk EKO, the associated gas processing unit, and the YANOS refinery can restore operations; whether Russia adjusts logistics to route more fuel from less‑exposed regions; and if Ukraine expands its campaign to additional energy nodes. Any sign of broad, sustained outages — especially if coupled with further Western sanctions on Russian refined products — would move this from a tactical pressure point into a structural strain on Moscow’s war economy.
