Ukrainian forces have advanced north from Kharkiv to within 50km of the border with Russia and are also pressing to the south and east in the same region, Ukrainian chief commander General Valeriy Zaluzhnyi said.
As the war in Ukraine marks 200 days, the military has reclaimed swaths of the south and the east in a long-anticipated counterattack that dealt a heavy blow to Russian forces.
Operations at the Russian-held Zaporizhzhia nuclear plant in Ukraine have stopped as a safety measure as fears of a radiation disaster continue.
Ukraine says its forces are working to wrest control of towns and villages around the strategic hub of Izyum from Russian troops as part of a counteroffensive in the country’s east.
Ukraine’s military in the Kherson region is seeking to drive Russian forces from their foothold on the west bank of the Dnieper River, a potential vantage point for a push deeper into Ukraine by Moscow.
