A fire broke out at an oil depot in Russia's southern city of Tuapse at night on Feb. 28, according to the city administration.
Local news outlet 93.ru previously reported two explosions on the oil depot territory, citing Tuapse residents.
The administration said the fire occurred in the depot's outbuilding, spreading at least 200 square meters. Local authorities added that the fire didn't affect oil tanks and was extinguished at about 3 am.
