MOSCOW, April 1. /TASS/. Eight fuel tanks are on fire at an oil depot in Belgorod, a source in the emergency services told TASS.

"Currently, eight fuel tanks are on fire with a volume of 2,000 cubic meters each. There is a threat of flames spreading," the source said.

Russia’s Emergencies Ministry added that the firefighting contingent had been increased to 170 people and 50 units of equipment.

On Friday, according to the region’s governor Vyacheslav Gladkov, two helicopters of the Ukrainian armed forces carried out two air strikes in Belgorod that caused a fire at the city’s oil depot. The flames engulfed the fuel tanks at the depot. The city’s authorities are evacuating residents from the buildings adjacent to the oil depot.
