KYIV, Ukraine—Ukraine has begun a counteroffensive toward the eastern city of Izyum, aiming to disrupt Russian supply lines into the Donbas region, officials said Saturday, as Ukrainian forces continued clearing villages north of the country’s second-largest city of Kharkiv.
As the war entered its 80th day, Russian offensive operations in Donbas remained largely stalled following the failure of Russia’s ambitious attempt to cross the Siverskyi Donets river and encircle the metropolitan area of Severodonetsk, the capital of the Ukrainian-administered Luhansk region.
