Ukrainian forces have launched a counteroffensive near the Russian-held town of Izium in eastern Ukraine, a regional governor said on Saturday, in what could prove a serious setback for Moscow's plans to capture the entire Donbas region.
Russian forces have focused much of their firepower on the Donbas in a "second phase" of their invasion that was announced on April 19, after they failed to reach the capital Kyiv from the north in the early weeks of the war.
