Ukrainian drones attack two oil refineries in southern Russia - source

Ukrainian drones attacked the Ilsky oil refinery in Russia's southern Krasnodar region, causing a large fire at the site on Friday in an operation conducted by the SBU security service, a Ukrainian source told Reuters.

The source who declined to be identified said SBU drones had also attacked Russia's nearby Afipsky oil refinery, but that the results of the operation were still being clarified.

Regional authorities in Russia said earlier that a fire had broken out at the Ilsky oil refinery and been extinguished in around two hours. It gave no details of what caused the fire or its impact on the refinery's output.
