This question will resolve as positive if the Wikipedia article for the 2022 Russian invasion of Ukraine (or a similar article) describes some original areas of Russia (pre-2014) to be or to have been under the de facto control of the Ukrainian government, otherwise it will resolve as negative.
"The main axis of the initial advance centred in the direction of the town of Sudzha, located 10 kilometres (6.2 mi) from the border, which was reported by Russian milbloggers to have been mostly captured by Ukraine on 8 August."
"According to the Kursk governor, Alexei Smirnov, Ukraine controls 28 settlements along a front that is 12 km deep and 40 km wide. Some 2,000 Russians are living under Ukrainian control while another 121,000 have been evacuated and another 180,000 are awaiting evacuation."
@GustavoMafra Please resolve. By now it seems confirmed by both sides that internationally recognised parts of russia are now under de facto ukranian control.
