Several dozen firefighters have been tackling a fire in the Russian town of Azov today following a drone strike, officials said.
Several oil storage tanks were set ablaze by the attack early this morning in Russia's southern region of Rostov, which borders Ukraine.
Russia's ministry of emergency situations said on Telegram that the fire had spread across 5,000 cubic metres.
Vasily Golubev, governor of the Rostov region, wrote on Telegram that there were no casualties according to preliminary data.
These reports are yet to be verified.
If confirmed, it would be the second consecutive day of strikes on the region, after a suspected Ukrainian attack triggered a large explosion at an electricity substation overnight into Monday.
