KREMENCHUK, Ukraine—Russian forces battled Wednesday to surround the Ukrainian military’s last stronghold in a long-contested eastern province as shock reverberated from a Russian airstrike on a shopping mall that killed at least 18 people in the center of the country a day earlier.
Moscow’s battle to wrest the entire Donbas region from Ukraine saw Russia forces pushing toward two Luhansk province villages south of the city of Lysychansk while Ukrainian troops fought to prevent their encirclement.
