Both Ukraine and Russia on Sunday reported high casualties in Ukraine’s Donbas region, the focus of Moscow’s slow, long-running advance into its neighbor’s territory.

Much of the fighting in the east has centered on Bakhmut, largely destroyed in months of attacks and shelling by Russia during the year-old conflict.

Ukrainian President Volodymyr Zelensky said Russian forces had suffered more than 1,100 dead in less than a week of fighting near the city.

“In less than a week, starting from 6th March, we managed to kill more than 1,100 enemy soldiers in the Bakhmut sector alone, Russia’s irreversible loss, right there, near Bakhmut,” Zelensky said in his nightly video address.

He said Russian forces had also sustained 1,500 “sanitary losses” – soldiers wounded badly enough to keep them out of further action. Dozens of pieces of enemy equipment were destroyed as were more than 10 Russian ammunition depots.

Russia’s defense ministry said its forces were conducting further military operations in Donetsk region which, together with adjacent Luhansk region, makes up Donbas.

The ministry said Russian forces had killed more than 220 Ukrainian service members over the past 24 hours.

“In the Donetsk direction… more than 220 Ukrainian servicemen, an infantry fighting vehicle, three armored fighting vehicles, seven vehicles, as well as a D-30 howitzer were destroyed during the day,” the ministry said.

Ukraine said on Saturday that more than 500 Russian troops had been killed or wounded in a recent 24-hour period as they battled for control of Bakhmut.

Reuters could not independently verify the accounts of either side.

Russian forces and troops from the privately run Wagner group of mercenaries have captured territory in the eastern part of the city and outskirts to the north and south but have so far failed to encircle it.

Moscow says capturing Bakhmut would punch a hole in Ukrainian defenses and be a step toward seizing all of the Donbas industrial region, a major target.
