Ukraine said on Sunday that its forces were still advancing around the edges of Bakhmut, aiming to encircle the ruined eastern city after Moscow congratulated the Wagner private army and Russian troops for capturing it.

Russia said on Saturday it had completely taken Bakhmut, which, if confirmed, would mark an end to the longest and bloodiest battle of the 15-month war. Russian President Vladimir Putin praised his regular troops and the Wagner group.

On Sunday, however, a top Ukrainian general said Kyiv's forces still controlled what he accepted was an "insignificant" part of Bakhmut, although that would allow them to enter the city when the situation changed.
