An oil depot in Russia’s Belgorod region on the border with Ukraine is on fire after it was shelled on Saturday, the governor said, as strikes against the area mount.

“We are being bombed again. One of the shells hit the oil depot in the Belgorod region,” said regional governor Vyacheslav Gladkov.

He said emergency services were already on the scene, adding there was “no risk” of the fire spreading.

Gladkov posted a photo showing flames and plumes of black smoke billowing over a building.

The state news agency TASS quoted an emergency services source as saying that the burning depot was in the village of Razumnoye-71, near the city of Belgorod.

Last week, Russia lamented an increase in artillery and rocket attacks on its territory bordering Ukraine.

The Belgorod region has regularly come under fire.

The capital of the region, also known as Belgorod, was hit less frequently.

But on Friday a power plant in the city was set on fire by a Ukrainian strike, causing power outages.

This came a day after a rocket destroyed the top floor of an apartment building in the city of Belgorod without causing injuries.

An ammunition depot in the region was also destroyed on Thursday.

Earlier in the week, Ukrainian strikes cut power in the city of Shebekino in the same region. A 74-year-old woman died and several others were injured in the city.
