"In the direction south of Urozhaine they (Ukrainian troops) had success," military spokesman Andriy Kovaliov said on national television.
Kovaliov also reported fierce fighting in the northeastern Kharkiv region, and around an eastern village not far from Bakhmut, the city occupied by Russian forces in May after a bloody months-long struggle.
"The enemy conducted unsuccessful offensive actions in the area of Senkivka in Kharkiv region and Bohdanivka in Donetsk.
"In the Bakhmut direction, defensive forces (Ukraine) continue to conduct offensive actions to the south of Bakhmut."
Kyiv says its counter-offensive is progressing slower than it wanted because of vast Russian minefields and heavily-fortified Russian defensive lines.
