Drone attacks have disrupted electrical power and gas supplies and hit phone lines in Russia's Belgorod region along the border with Ukraine, Belgorod Governor Vyacheslav Gladkov reported on Monday.
"There is damage to phone cables, to the gas and electricity supply. Electricity has been cut in a string of villages," Gladkov posted on his Telegram channel.
He mentioned Grayvoron and Krasnaya Yaruga west of Belgorod City, and Shebekino to the south-east of the regional capital. All three villages lie virtually on the border with Ukraine.
Local media reported that Belgorod itself and the city of Oskol to the north-east of Belgorod had also been affected. They attributed the power outage to a damaged substation.
The Pepel website published video material showing explosions at a substation in Stary Oskol. The substation is one of the largest and supplies power to the neighbouring Kursk region as well, where the regional governor warned of shortages.
