Russian forces have been advancing far more quickly in Donetsk region in recent weeks than they did for the whole of last year, according to the Institute for the Study of War (ISW), whose map shows the state of play on the front line.

The Washington, D.C., think tank said on Sunday that recent Russian gains near Vuhledar and Velyka Novosilka showed that the war „is not stalemated“ and the Donetsk region is „becoming increasingly fluid“ with the latest Russian advances. Newsweek has emailed the Russian and Ukrainian defense ministries for comment.
