'Disinformation': Kyiv rejects claim Russian forces entered key region

Kyiv's armed forces rejected as "disinformation" Russia's claim that its ground troops have crossed into Ukraine's Dnipropetrovsk region for the first time, even as prospects for a US-brokered ceasefire remain elusive.

KYIV/MOSCOW:

Separately, Ukraine and Russia continued testy exchanges over the details of a planned large prisoner swap agreed to during last week's talks in Turkey. The exchange is likely to move ahead in the coming days.

Russia's defence ministry said on Sunday that units of its 90th tank regiment had crossed the western administrative border of Donetsk into neighboring Dnipropetrovsk, in what would be a symbolic milestone in their years-long offensive.

In response, Ukraine's southern defence forces said its troops were "holding their section of the front" while involved in a situation that, while "tense", is still contained within the Donetsk region.
