Gladkov said that the drone had attacked a bus belonging to an agricultural enterprise in the village, which is close to the border with Ukraine's Sumy region.
Belgorod region has come under regular Ukrainian drone, artillery and ground attacks since Moscow ordered tens of thousands of troops into Ukraine in February 2022.
