"The Ukrainian Armed Forces attacked an oil depot in the Gubkinsky urban district using drones. As a result of an explosion, one of the tanks caught fire. Fire crews quickly extinguished the fire," Gladkov said.
He said there were no casualties.
Meanwhile Russia's southern Rostov Region was attacked by 55 Ukrainian drones overnight, Governor Vasily Golubev revealed.
"This night, the territory of the Rostov Region was attacked by 55 Ukrainian unmanned aerial vehicles. As a result of the attack there were no casualties or injuries," Golubev said.
Russia has been conducting a special military operation in Ukraine since February 24, 2022. President Vladimir Putin has said the operation aims to "protect people subjected to genocide by the Kiev regime for eight years." According to the president, the ultimate goal of the operation is to liberate Donbas and create conditions that guarantee Russia's security.
The Kiev regime has increasingly launched attacks on territory in Western Russia in recent months, often resulting in civilian casualties.
