Ukrainian forces outside the battered eastern city of Bakhmut are managing to keep Russian units at bay so ammunition, food, equipment and medicines can be delivered to defenders, the army said on Saturday. And in the latest claim to have inflicted heavy casualties, Kyiv said its troops had killed 193 Russians and injured 199 others during the course of fighting on Friday. Russia has made the capture of Bakhmut a priority in its strategy to take control of Ukraine's eastern Donbas industrial region. The city has been largely destroyed in months of fighting, with Russia launching repeated assaults.
