Ukrainian forces now control up to 1,000 square kilometers of land and more than 70 settlements inside Russia.
Shocking footage has emerged of the moment Ukrainian paratroopers made an extraordinary bid to smash the international border with Russia by driving at full speed in a Kozak 2 armoured vehicle.
Ukrainian soldiers have ambushed a truck filled with Russian troops as they continue their Kursk offensive.
Mr. Putin has said nothing about the incursion since meeting with security and regional officials, a tense gathering in which the president at one point berated the Kursk governor for revealing the depth and breadth of Ukraine’s advance into Russia.
