"As a result of a missile attack with cluster munitions on Sverdlovsk, a fuel and lubricants storage facility was damaged," Leonid Paschanik, the head of pro-Russian separatist forces in the Luhansk region, wrote on the High Telegram channel on Monday.
Ukraine renamed the small city of Sverdlovsk, which has been occupied by Russian forces since 2014, to Dovzhansk in 2016.
According to Ukrainian media, a Russian military base was also targeted in the missile attack.
Videos on social networks showed thick clouds of smoke, but also a burning multi-storey barracks-style building.
Russian officials on the ground have not officially released any information on casualties or injuries.
Ukraine has been fending off a full-scale Russian military invasion for more than two years.
Kiev has recently fired missiles at oil processing plants and fuel depots in addition to purely military targets to disrupt Russian military logistics.
