"During the past day, the armed forces of Ukraine continued unsuccessful attempts of offensive actions in the Donetsk, southern Donetsk and Zaporizhzhia directions," it said.
Russian military bloggers said Ukrainian forces had smashed through a section of the Russian lines south of the town of Velyka Novosilka, briefly taking several villages as Russian forces retreated to higher ground.
Vladimir Rogov, a Russian-installed official in the part of the Zaporizhzhia region controlled by Russia, said Russian forces had then taken the village back.
Ukraine has said it made gains near Bakhmut, which fell to Russia last month.
Russia's defence ministry published several videos and pictures over recent days showing numerous strikes on Ukrainian-manned armoured vehicles and tanks from Ka-52 attack helicopters and drones.
