Ukraine has publicly justified its attack into Russian territory for the first time, amid reports that its forces are advancing towards a village 13 miles (20km) inside the Kursk region on the third day of its incursion.
Mykhailo Podolyak, a senior adviser to the president’s office, said “the root cause of any escalation”, including into Kursk, was “unequivocal aggression” on the part of Russia in believing it could invade Ukraine with impunity.
