Ukrainian forces attacked an oil refinery in the Russian city of Ryazan and an oil depot in occupied Luhansk during the night of 5 September, Robert Brovdi, commander of Ukraine's Unmanned Systems Forces, said.
The Ryazan Oil Refinery, one of Russia's four largest refineries, was struck by Ukraine's 14th Unmanned Systems Regiment together with Special Operations Forces, Main Intelligence Directorate, and other Defense Forces components. The same regiment targeted the Luhansk oil depot.
Russian Telegram channel Astra earlier cited eyewitnesses reporting that the Ryazan refinery was burning following drone strikes. Ryazan region governor Pavel Malkov claimed that eight drones were shot down over the region overnight, with debris falling on an industrial facility.
Russian media and Telegram channels reported a large fire in occupied Luhansk on the evening of 4 September. The strike reportedly hit a key oil depot that supplies fuel to Russian forces.
Ukrainian drone attacks on Russian oil refineries have occurred regularly since the beginning of 2024. Some facilities have sustained damage to primary oil processing units requiring repairs.
Ukraine's General Staff has confirmed most attacks, stating that the Defense Forces "systematically implement measures aimed at reducing the combat potential of Russian occupation forces, as well as forcing the Russian Federation to cease armed aggression against Ukraine."
