Falling drone debris sparked a blaze at the Afipsky oil refinery in Russia's southern Krasnodar region, but the fire has been contained, regional authorities said on Saturday.
Some technical equipment on the premises has been damaged, but the tanks have not been affected, the local taskforce said.
The Russian Defense Ministry said that air defense units had intercepted and destroyed 103 Ukrainian drones over Russian regions overnight, including 11 over the Krasnodar region, reported Reuters.
