Heavy frontline battles persist as Ukrainian forces advance near Kupiansk

Heavy fighting continues across eastern Ukraine, with the Ukrainian General Staff reporting over 250 combat engagements within a single day. Russian forces mounted intense assaults in the Pokrovsk, Lyman, and Kostiantynivka sectors, where defensive positions faced repeated attempts to breach Ukrainian lines.

Despite heavy pressure, Ukrainian troops executed infantry clearing operations north of Kupiansk along the right bank of the Oskil River, leveraging electronic warfare to disable Russian drone capabilities. Conflicting reports persist along other frontline sectors: Russian defense officials claimed control over settlements near Sumy and denied Ukrainian advances in Zaporizhzhia, while independent military observers highlighted potential Ukrainian gains around Lyman.
