Russia said on Friday that its forces had taken control of Soledar in eastern Ukraine, in what would be a rare success for Moscow after months of battlefield reverses, but Kyiv said its troops were still fighting in the town.

The situation in Soledar, a small salt-mining town that has for days been the focus of a relentless Russian assault, could not be immediately verified.

Kyiv and the West have played down the town's significance, saying Moscow sacrificed wave upon wave of soldiers and mercenaries in a pointless fight for a bombed-out wasteland, unlikely to affect the wider war except insofar as the huge losses have sapped manpower on both sides.
