Ukrainian defense forces struck two Russian oil refineries overnight on 30 August using unmanned aerial vehicles, targeting facilities in Krasnodar Krai and Samara Oblast, according to the General Staff of Ukraine.

The strikes hit the Krasnodar refinery in Krasnodar Krai and the Sizran refinery in Samara Oblast. Ukrainian forces conducted the operations “within the framework of reducing the Russian offensive potential and complicating fuel supplies to occupying forces’ military units,” the General Staff reported.

The Krasnodar refinery produces 3 million tons of light petroleum products annually, including gasoline, diesel, and aviation fuel, and “participates in supplying the Russian Armed Forces,” according to the General Staff. The facility sustained damage to one technological installation and a fire covering approximately 300 square meters, regional emergency services reported.

According to the regional operational headquarters, due to falling drone debris on the territory of the Krasnodar refinery, one of the technological installations was damaged, a fire occurred over an area of about 300 square meters.

The Sizran refinery was struck for the second time, military officials said. The facility produces gasoline, diesel fuel, aviation kerosene, fuel oil, and bitumen, with processing volumes reaching 8.5 million tons annually as of August 2025, the General Staff reported.
