Volodymyr Zelenskyy has said Ukraine now controls more than 1,300sq km in the Kursk region.
Meanwhile, Ukraine's top military commander Oleksandr Syrskyi told CNN that the operation in the Kursk region was working and that there had been no Russian advances on a key sector of the eastern front for six days.
"Over the last six days, the enemy hasn't advanced a single metre in the Pokrovsk direction. In other words, our strategy is
working," he said.
Mr Syrskyi said the military had also noted a decrease in shelling and the intensity of the Russian offensive in other sectors.
