Ukrainian troops have advanced up to 30km inside Russia, in what has become the deepest and most significant incursion since Moscow began its full-scale invasion of Ukraine in February 2022.
Russia's defence ministry said its forces had engaged Ukrainian troops near the villages of Tolpino and Obshchy Kolodez, as the offensive in the Kursk region entered a sixth day.
A senior Ukrainian official told the AFP news agency that thousands of troops were engaged in the operation, far more than the small incursion initially reported by Russian border guards.
Ukrainian troops have claimed to have captured a number of settlements in the Kursk region.
Meanwhile, aerial photos have appeared to show Ukrainian tanks engaged in combat inside Russia. »
