Ukrainian forces reportedly conducted successful drone strikes against an oil refinery and Russian military airfields in Saratov, Ryazan, and Murmansk oblasts on the night of July 26 to 27. Sources with Ukrainian special services told Ukrainian media that Ukraine's Main Military Intelligence Directorate (GUR) struck Russian military airfields in Engles, Saratov Oblast; the Dyaghilev Airfield and an oil refinery in Ryazan Oblast; and the Olenya Airfield in Murmansk Oblast with drones. Suspilne's sources reported that Russian forces base an unspecified number of Tu-95, Tu-22, Tu-134, and Il-78 (tanker) aircraft at the Dyaghilev Airfield and that the GUR drones damaged a TU-22M3 strategic bomber at the Olenya Airfield. Russian officials, including the Russian Ministry of Defense (MoD), claimed that Russian air defenses destroyed an unspecified number of drones over Saratov and Ryazan oblasts, although Russian sources published footage of Ukrainian drones operating over Ryazan City. Additional sources told Suspilne that GUR "sabotage activities" damaged an Mi-28 and a Ka-226 helicopter at an aircraft construction enterprise in Moscow Oblast on July 21 and destroyed another Mi-8 helicopter at the Kryazh Airfield in Samara Oblast on July 24. Ukrainian Commander-in-Chief Colonel General Oleksandr Syrskyi stated during an interview with UK outlet The Guardian published on July 24 that Ukrainian drones had targeted around 200 critical infrastructure sites connected to military logistics in rear areas of Russia since the start of the full-scale invasion.
