A new Guardian analysis of Institute for the Study of War data shows that, after once having seized as much as 51,000 sq miles (132,000 sq km) of Ukrainian land, Russia has since lost a fifth of this.
It now controls 40,000 sq miles of Ukrainian land, entirely in the south and east. This is 17% of Ukraine – a country of 230,000 sq miles, or twice the size of Italy.
The analysis shows that Russia still controls a majority of the land in each of the four regions it attempted to illegally annex last year — Luhansk, Kherson, Zaporizhzhia and Donetsk.
