Ukraine's military said on Wednesday that Russian President Vladimir Putin's claims about the town of Kupiansk being surrounded by Russian troops were "fantasies", Reuters reported.
Putin made the claim about the northeast Ukrainian town earlier in the day.
Ukraine's Joint Forces Task Force said Russian troops were in the northern part of the city but that claims about an encirclement were untrue.
DeepState, a Ukrainian open-source battlefield mapping project, did not appear to show an encirclement in Kupiansk.
