Russian troops are attempting to encircle the strategic city of Kostyantynivka in eastern Ukraine, which is crucial for controlling the Donbas region. Despite claims from Moscow of rapid advances, Ukrainian officials maintain that the situation is under control, although they acknowledge the presence of Russian soldiers within the city. The ongoing conflict has led to significant logistical challenges for Ukrainian forces, raising concerns about the potential fall of Kostyantynivka and its implications for the broader war effort.
