Ukraine’s long-range drone fleet has launched another highly effective overnight assault against the Russia’s domestic energy network in the early Sunday morning, May 31, executing successful deep-strike operations that left a key Rosneft oil refinery and an inland fuel depot heavily ablaze, DW and Exilenova+ Telegram channels reported. Rosneft refinery targeted in Saratov The most economically damaging blow was delivered in the Saratov region, where Ukrainian strike assets successfully bypassed local electronic warfare shields to strike the Saratov Oil Refinery (NFP). Operating as one of the most critical energy processing hubs in the Volga River region, the Rosneft-owned plant is a primary producer of high-grade gasoline, diesel fuel, and specialized petroleum products for the Russian domestic market.JOIN US ON TELEGRAMFollow our coverage of the war on the @Kyivpost_official.
Saratov Regional Governor Roman Busargin initially attempted to downplay the strike, releasing a vague statement via Telegram claiming that “objects of civilian infrastructure were damaged” but omitting specific names. However, independent OSINT analysis conducted by the Russian outlet ASTRA dismantled the official narrative. By cross-referencing geolocation data from local eyewitness footage captured on Sokolova Street – roughly 12 kilometers away – analysts confirmed multiple large-scale blazes erupting directly within the plant’s main fuel tank farm. Preliminary field assessments indicate that at least one drone directly impacted the refinery’s vital isomerization unit, a technical node crucial for manufacturing high-octane fuels. Local authorities later confirmed that specialized emergency crews were deployed to combat the multi-point structural fire.
