A Russian oil depot in the Rostov region has started burning after being attacked by a Ukrainian drone, writes the region's governor Vasilij Golubev on the Telegram platform.
No one has been injured, according to Golubev.
The oil depot is located tens of miles from the front line where the war between Ukraine and Russia is taking place.
According to Russia's Defense Department, Russian forces have simultaneously shot down Ukrainian drones in Rostov and in the regions of Belgorod and Kursk.
In June, a major fire broke out at an oil facility in Russia, about eight miles from the Ukrainian border, after a Ukrainian drone attack.
