A Russian-installed official confirmed that Ukraine had retaken a village in the southern Zaporizhzhia area, marking the country’s second success on that front since it began its counteroffensive earlier this month.

The official, Vladimir Rogov, reported that Russian artillery fire was coming at Ukrainian soldiers while they were fortifying themselves in the town of Piatykhatky.

“The enemy’s ‘wave-like’ offensives yielded results, despite enormous losses,” Rogov said on the Telegram messaging app.

Heavy fighting continues in the area, he added. There was no immediate comment from Ukraine, and Reuters could not independently confirm the situation on the battlefield.

Russia says it is inflicting heavy losses on Kyiv’s forces and President Vladimir Putin said last week that Ukraine had “no chance” of success in the counter-offensive.

Ukraine said last week it had regained control of about 100 square km (38 square miles) of territory in just over a week, recapturing a string of villages in Donetsk region to the east.

Ukraine said on June 12 it had taken control of Lobkove, a village adjacent to Piatykhatky in Zaporizhzhia region.
