At least five people were wounded in Ukrainian shelling in southern Russia's Belgorod region district, Governor Vyacheslav Gladkov announced, DPA reported, quoted by BTA.
Several grenades hit a section of the road between Belgorod and Shebekino, injuring four people and damaging several cars. In the nearby village of Voznesenkovka, a woman was injured when a drone struck a house.
The information cannot be independently verified.
The Ukrainian army began using artillery and drones to attack targets across the border after Moscow's forces launched an offensive against the northeastern city of Kharkiv in the summer, DPA said.
Russia also regularly attacks civilian objects in Ukraine, with Kharkiv - which is only 30 km from the border - being among the cities most often targeted by Russian shelling, the agency added.
