Russian forces are pressing renewed offensive operations in eastern Ukraine despite brutal winter conditions, with intense fighting centered around the strategic city of Pokrovsk. Ukraine’s Commander-in-Chief Oleksandr Syrskyi says Moscow is reinforcing the front with fresh reserves and using infiltration-style tactics to breach defenses. Although Russian advances slowed in January due to freezing temperatures, hundreds of clashes have been recorded as Russia pushes north of Pokrovsk. The battle for the “Gateway to Donetsk” is shaping up as one of the most critical tests of endurance and strategy in the war, with major implications for control of the Donbas region.
