Ukraine has staged a counterattack on the frontline city of Sievierodonetsk and recaptured a fifth of the city it had previously lost to Russian invaders, according to the head of the region.
Serhiy Haidai, the governor of Luhansk oblast, told Ukrainian television that Russian forces were forfeiting recent gains in the city, the easternmost held by Kyiv in the Donbas region, where fighting has been concentrated.
