Ukraine's military said its forces had repelled an attack in the area of Blahodatne in the eastern part of the Donetsk region, while Russia's Wagner private military group said it took control of the village.
"Units of Ukraine's Defence Forces repelled the attacks of the occupiers in the areas of ... Blahodatne ... in the Donetsk region," the General Staff of Ukraine's Armed Forces said in its daily morning report, referring to fighting yesterday.

With fighting heating up in the Donetsk region, the exact line of contact has been unclear, especially around the town of Bakhmut, were some of the heaviest fighting of the war has been taking place in recent weeks.
The Wagner Group has made premature success claims before.
Ukraine has said that the Russian offensive on Bakhmut has not culminated, but the situation along the front line there has been growingly difficult.
President Volodymyr Zelensky said on Friday that it was acute.
Four civilians were killed, one in Bakhmut, and 17 wounded in Russian attacks on the region yesterday, Pavlo Kyrylenko, governor of the Donetsk region said on the Telegram messaging app.
Ukraine has won promises of Western battle tanks and is seeking fighter jets to push back against Russian and pro-Moscow forces, which are slowly advancing along part of the front line.
Yesterday, President Zelensky's top aide said that expedited talks were under way between Ukraine and its allies about its requests for long-range missiles to prevent Russia from destroying Ukrainian cities.
