Ukraine has made its largest battlefield gains in more than two-and-a-half years, retaking more than 200 square kilometres of it's territory from Russia last week.

That's according to a report by the news agency Agence-France Presse, which used data from the Institute for the Study of War.

It comes as the latest round of United States-brokered peace talks between Kyiv and Moscow ended in gridlock overnight.
