TASS reported that Russian forces claim full control of Kupiansk a few days after Volodymyr Zelensky visited frontline troops near the city, while Kyiv says it recently pushed back Russian units there.Leonid Charov, a Zapad grouping spokesman cited by TASS, said the Russian 6th Army controls the city but conceded that small Ukrainian groups attempt daily incursions and that all neighborhoods are under Russian control.Independent reporting describes recent Ukrainian counterattacks using local defences and electronic countermeasures to neutralize attack drones and exploit gaps in overextended Russian lines, and analysts say the competing claims reflect the fog of combat and may be aimed at influencing peace talks with the United States and the EU.
