A Nato official has said there is so far "no indication" that Russian forces have withdrawn from near the Ukrainian border.
Vladimir Putin earlier said the Kremlin had pulled back its forces and they were "not on the Ukrainian border".

"We have no indication of a change in the position of military forces along the Ukraine border," the official said.
European Union foreign ministers added 13 people to their visa ban and asset freeze list over Ukraine's crisis.

Nearly 90 percent of voters in eastern Ukrainian region voted for self-rule, the head of the separatist election commission said.
