Drone Strikes Hit Russian Oil Refineries in April: Fires Reported in Yaroslavl, Ufa, and Tolyatti

Unmanned Aerial Vehicle Attacks Target Industrial Sites Across Russia

According to Главком: Throughout April 2025, a wave of drone attacks struck multiple industrial facilities in Russia. On April 26, 2026, unmanned aircraft hit the Yaroslavl Oil Refinery, located in the city of Yaroslavl. Local residents reported hearing more than 15 explosions, and a fire subsequently broke out at the plant.

Earlier, on April 18, 2026, the Samara region experienced a large-scale drone assault. The primary target was the city of Novokuibyshevsk, where the first blasts occurred around 4:30 a.m. local time. Witnesses in the northern and eastern parts of Novokuibyshevsk described a series of 6 to 8 explosions.

• On April 4, 2026, another massive drone attack took place in the Samara region, with industrial sites in the city of Tolyatti as the main objectives.
• On April 2, 2026, the Bashneft-Ufa Oil Refinery in Ufa-an asset of Bashneft, which is part of Rosneft-also became a drone target. This facility processes a blend of crude oil from Western Siberia (50%), local Bashkir oil (40%), and gas condensate.

These drone strikes on Russian industrial assets highlight a growing threat to the country's critical infrastructure. Given that oil refineries are vital to energy security, such incidents carry significant economic implications. Amid ongoing political instability and rising regional tensions, these attacks are likely to prompt enhanced security measures and shifts in industrial strategic planning.

As these drone strikes continue to escalate, the focus on Ufa has intensified, marking the city as a significant target in this wave of attacks. For a closer look at the implications of these incidents and how they relate to the broader pattern of assaults on energy infrastructure, see more about the recent drone strike in Ufa.
