Ukraine has claimed that it has taken control of 100 Russian settlements sprawling in an area of 1,294 kilometers of Russian territory, BBC reported.
Ukrainian President Zelensky last week said his armies had taken over 1,250 sq km of Russian territory, following the incursion into the Kursk region that began three weeks ago.
Similarly, Ukraine's commander in chief Oleksandr Syrskyi also said that Ukraine has captured 594 Russian soldiers.
Earlier, Russia launched another wave of strikes on Ukraine, with four people killed, a day after one of its biggest air attacks of the war.
Meanwhile, Zelensky has warned that Kyiv will "undoubtedly respond to Russia for this and all other attacks.”
It's been three weeks since Ukraine launched a lightening offensive into Russian territory - the deepest into Russia since Moscow launched its full-scale invasion in 2022.
The surprise move is said to have involved 10,000 elite Ukrainian troops, and took ground quickly.
But the pace of the advance has since slowed.
Russia has vowed to respond - the nature of that has not been specified, but the last two days have seen an increase in aerial attacks on Ukraine.
