Ukraine's military has rejected Russian claims that its troops have reached the suburbs of the town of Chasiv Yar in the Donetsk region.
It did note fighting in the area, however.
"The situation there is very difficult, the fighting continues, but they [Russian troops] are not there," Andriy Zadubinnyi, spokesman for Ukraine's eastern command, told the Reuters news agency.
"Don't believe the Russian reports."
This comes after Russian state news agency RIA cited an adviser to the Moscow-installed regional head of the region as saying that the Kremlin's forces had arrived in the suburbs.
