Kyiv launched a shock incursion into Russia's Kursk border region on Aug 6, advancing kilometres into Russian territory and seizing dozens of settlements.
Units of the 'North' group of troops liberated 10 settlements within two days,' Russia's defence ministry said in a statement posted on its Telegram channel.
Two years ago a major Ukrainian counteroffensive got underway that saw the Armed Forces of Ukraine (AFU) simultaneously attack Russian positions in the Kharkiv, Donetsk and Luhansk regions, liberating large swathes of territory.
Moscow’s forces claim to have started an offensive to dislodge Ukrainian troops in the Kursk region of Russia, their first significant effort in more than five weeks since the start of Kyiv’s incursion.
