The Slavyansk oil refinery in Russia's Krasnodar region was damaged in a Ukrainian drone attack, local authorities said on Saturday.
Roman Siniagovsky, head of the Slavyansk Administrative Region, said via the Telegram app that a total of nine attacks had occurred on the tank farm and the distillation column.
“The tank farm was not damaged due to the organized protection system. The distillation column was damaged. The fire was eliminated through the joint efforts of the responsible agencies,” Siniagovsky said.
Local emergency services said a fire broke out in a small area of the refinery and was later extinguished.
The Russian Ministry of Defense said on Saturday that its air defense units intercepted and destroyed 66 Ukrainian drones over the territory of the Krasnodar region, and two other drones over the Crimean Peninsula.
