Ukrainian forces attacked Russia's western Kursk region on Monday, firing missiles, smashing through the border and then crossing minefields with special vehicles, according to Russian war bloggers. Russia's top general said last month that Ukrainian troops had been ejected from the Kursk region, ending the biggest incursion into Russian territory since World War Two, and that Russia was carving out a buffer zone in the neighbouring Ukrainian region of Sumy. The Ukrainian attack in Kursk was reported by multiple other Russian bloggers including "The archangel of special forces" and Russian state television war correspondent Alexander Sladkov.
