KEY TAKEAWAYS

• Ukrainian drones struck the Slavneft-YANOS oil refinery in Russia’s Yaroslavl region.
• Regional authorities confirmed a fire at the facility following the attack.
• President Volodymyr Zelenskyy said Ukraine also targeted another refinery in Bashkortostan.
• The Yaroslavl refinery is one of Russia’s largest, with an annual processing capacity of about 15 million metric tons.

Ukraine carried out a long-range drone strike on one of Russia’s largest oil refineries, setting part of the Slavneft-YANOS facility in the Yaroslavl region on fire, according to Russian regional authorities. The refinery, located around 250 kilometers northeast of Moscow, is considered an important part of Russia’s fuel production network and has previously been targeted by Ukrainian drones.

Strategic Energy Infrastructure Targeted

Yaroslavl Governor Mikhail Yevrayev said drone debris caused a fire at the refinery after Russian air defenses attempted to intercept incoming drones.

Ukraine later confirmed that the Yaroslavl refinery was among the intended targets of its overnight operation, describing the strikes as part of its campaign against facilities supporting Russia’s war effort.

One of Russia’s Largest Refineries

The Slavneft-YANOS refinery processes approximately 15 million metric tons of crude oil annually, making it one of the country’s largest refining facilities.

It supplies gasoline, diesel fuel, aviation fuel, and other petroleum products to domestic and international markets, giving it strategic importance for Russia’s economy.

Ukraine Expands Deep-Strike Campaign

President Volodymyr Zelenskyy said Ukrainian forces also struck another major refinery in Bashkortostan during the same operation.

Over the past year, Ukraine has increasingly targeted oil refineries, fuel depots, and logistics hubs deep inside Russia in an effort to disrupt fuel production and increase pressure on Moscow’s wartime economy.

Russia Reports Massive Drone Attack

Russian authorities said air defenses intercepted dozens of drones across multiple regions during what officials described as one of the largest drone attacks in recent months.

Emergency services responded to the refinery fire, while authorities reported no fatalities at the Yaroslavl facility, although several people were injured elsewhere in the region by falling debris.

WHY IT MATTERS

Ukraine’s long-range drone campaign increasingly focuses on energy infrastructure that generates revenue for Russia’s economy and supports military logistics. Repeated strikes on major refineries have forced temporary production disruptions, increased repair costs, and highlighted the vulnerability of strategic facilities located far from the front line.

WHAT’S NEXT?

Russian authorities are assessing the extent of the damage and whether refinery operations will be affected. Meanwhile, Ukraine is expected to continue targeting strategic energy infrastructure as part of its broader campaign to weaken Russia’s wartime industrial capacity.
