A drone strike sparked a fire at an industrial facility in Russia’s Surgut district, which Ukrainian monitoring channels identified as Gazprom’s Surgut Condensate Stabilization Plant.

The plant can process up to 12 million tonnes of oil and gas condensate a year, producing gasoline, diesel and jet fuel.

It lies about 2,400 km from Ukraine’s border, making this one of the farthest reported strikes on Russian energy infrastructure.
