Ukraine struck sites in the Russian regions of Oryol, Saratov and Rostov overnight on November 7, hitting an oil refinery among several targets, The Kyiv Independent reported, citing monitoring channels. The Saratov Oil Refinery was set ablaze after it was targeted by Ukrainian forces, according to the monitoring channel Exilenova Plus, the outlet said, adding that the details could not be immediately verified.

In Saratov, regional governor Roman Busargin said the drone attack had caused damage to civilian infrastructure and that preliminary casualties were reported, according to Russian military-news outlet Topwar, summarising the governor's statement and Kommersant reporting. No confirmed casualty toll had been published in the first reports.

In the western city of Oryol, the Proton electronic components factory was targeted, with local channels alleging that Ukraine's Flamingo missiles were used in the attack, according to Exilenova Plus via The Kyiv Independent — an allegation that has not been independently verified. Oryol regional governor Andrey Klychkov said that repelling a massive missile attack had damaged the production facilities of a company in the city's Sovetsky district, but he did not name the company, Topwar reported, citing the governor and Kommersant.

In Rostov, a large fire broke out in the area of the Almaz military factory, The Kyiv Independent reported, while Ukrainian forces reported a fire at an oil and polymer warehouse covering an area of approximately 8,000 square metres, according to Topwar's summary of the Ukrainian account — a figure that likewise remains unverified.

Part of a wider refinery and war-industry campaign

The overnight reports fit the campaign President Volodymyr Zelenskyy described on Friday, when he said Ukraine would continue its strikes against Russia's oil refining industry in response to Russian attacks on Ukrainian energy facilities. Ukrainian open-source channels say the Proton plant produces semiconductor and power electronics used in Russian weapons, including Iskander-M missiles and Pantsir-S1 air defence systems — a claim about the plant's role that those channels, not independent assessors, have made. The Saratov refinery, one of Russia's oldest oil-processing plants, has been struck repeatedly during the war.

What happens next: Ukraine's General Staff commonly confirms or details deep strikes inside Russia later in the day, and Russia's defence ministry usually publishes interception figures; neither had issued a full account in the first reports reviewed for this story. Damage assessments from satellite imagery and local authorities are expected to clarify which facilities were hit and how badly.
