"Fire and rescue crews were sent to the location… Upon arrival, they confirmed that there was a fire on the territory of the oil depot," the local branch of the Russian Emergencies Ministry said in a statement.
At the start of April, a fire was reported at an oil depot in the Russian city of Belgorod, located about 40 kilometers (25 miles) from the Ukrainian border.
Governor of the Russian Belgorod Region Vyacheslav Gladkov said that the fire was caused by airstrikes carried out by two Ukrainian military helicopters that entered the Russian airspace at low altitude.
According to the mayor of Belgorod, Anton Ivanov, none of the oil depot employees were injured.
