Ukraine has staged a counterattack on the frontline city of Sievierodonetsk and recaptured a fifth of the city it had previously lost to the Russian invaders, according to the head of the region.
Serhiy Haidai, governor of Luhansk, said Russian forces were giving up recent gains in the city, as reports also emerged of foreign fighters joining the battle for the easternmost city held by Kyiv in the fiercely contested Donbas.
