A Ukrainian drone attack on the Slavneft-Yanos oil refinery in Yaroslavl resulted in one fatality and 27 injuries, according to local authorities. The attack ignited a fire at one of Russia's largest oil refineries, which is vital for supplying fuel to the Russian military.1

Yaroslavl region Governor Mikhail Yevrayev reported that the casualties were caused by falling drone debris that struck an intercity bus. He also noted that debris impacted residential areas and commercial properties, raising concerns about civilian safety.2

Russia's Defense Ministry claimed to have intercepted 512 Ukrainian drones across Russia and annexed Crimea overnight, indicating a significant escalation in drone warfare. Ukraine's military confirmed the strike on the refinery, emphasizing its role in providing fuel and lubricants for Russian military operations.3

The Slavneft-Yanos refinery, part of the public joint-stock company Slavneft, has a capacity of approximately 15 million metric tons of crude oil per year and produces various petroleum products, including automotive gasoline and jet fuel. This facility has been targeted multiple times this year, with Friday's attack marking at least the seventh strike.

Ukrainian President Volodymyr Zelensky later confirmed the attack and mentioned that Ukraine's SBU security service had also targeted a Tu-95MS missile-carrying aircraft in Engels, further highlighting Ukraine's ongoing military operations against Russian assets.

In addition to the Yaroslavl incident, separate Ukrainian attacks in the Belgorod region resulted in two deaths and nine injuries, showcasing the broader impact of the conflict across multiple regions.
