Ukraine makes breakthrough in south against Russia- By Laurence Peter and Matt Murphy- BBC NewsUkrainian troops have retaken more territory in regions illegally annexed by Russia, with Kyiv's forces advancing near the southern city of Kherson and consolidating gains in the east.The progress of Ukraine's counterattacks have been closely guarded and reporters have largely been kept away from the front lines.Russian defence ministry spokesman Igor Konashenkov said "numerically superior" Ukrainian tanks had "driven a deep wedge" south of Zolota Balka, a village that marked the previous front line on the Dnipro.On Monday, Kremlin spokesperson Dmitry Peskov attracted ridicule online after he admitted that Russia was still deciding which areas it had "annexed", suggesting that Moscow does not know where its self-declared borders are.Mr Peskov claimed the entirety of Luhansk and Donetsk regions were part of Russia, but said the Kremlin would "continue consultations with the population regarding the borders of the Kherson and Zaporizhzhia regions"."
