Ukraine claims control of key Oskil river on front line
Ukrainian forces say they have regained control of the east bank of the River Oskil, seen as the front line with Russian troops in north-east Ukraine.
Russia's army has been almost completely pushed out of the Kharkiv region and a regional leader said the next target would be neighbouring Luhansk.
President Volodymyr Zelensky said the next offensive was being prepared.
