The western and northern parts of Vovchansk in Ukraine's Kharkhiv region have fallen under the control of Russian forces, the TASS state news agency reports.
Ukraine's military has said the situation in the town of Vovchansk is under control but it had to withdraw to new positions near the village of Lukyantsi due to heavy Russian air strikes.
Street fighting is ongoing in the town, TASS reports.
The embattled town of Vovchansk, in northeast Ukraine, is where Kyiv's troops are locked in intense battles with the Russian army.
The town, whose pre-war population of 17,000 had dwindled to just 2,500 before Russia renewed its ground assault last week, has emerged as a focus point for Russia.
