Ukrainian drones hit two Russian oil refineries and defence-linked plants overnight into 25 September
In the night of 24–25 September 2026, Ukrainian drones struck multiple Russian industrial sites far behind the front line. The Lukoil-Permnefteorgsintez refinery in Perm was hit and a fire broke out; the Novoshakhtinsk refinery in Rostov Oblast suspended operations after being damaged; the Iskra microelectronics plant in Ulyanovsk, part of the Almaz-Antey defence concern, was also struck, along with a synthetic-rubber plant in Voronezh. Russia's General Staff of the Armed Forces of Ukraine confirmed the strikes on the two refineries, and President Volodymyr Zelensky publicly acknowledged the attacks.
