The OSCE's envoy to Ukraine warned Friday that while there were encouraging signs of a cease-fire taking hold in east Ukraine, the country still faced the threat of all-out war.

Swiss diplomat Heidi Tagliavini told the U.N. Security Council that fighting was subsiding in east Ukraine, prisoners had been released and the withdrawal of heavy weapons had begun.

But she emphasized that the situation remained volatile and recent "encouraging signs" could be reversed.

"We seem to be at the crossroads, where we are facing the risk of a further escalation of the conflict or where common sense, responsibility, and humanity shall prevail and we may be able to walk on the road to peace," Tagliavani told the 15-member council.

Three Ukrainian soldiers were killed in clashes between Kiev's forces and pro-Russian rebels Friday, after two days in which no deaths were reported.

"Unless the guns fall silent there will be no hope for stabilizing the situation let alone for peace," Tagliavini told the council by video link.

"We know that we are far away from this goal."

The envoy said providing humanitarian aid to the one million people displaced from the conflict would be a priority once the cease-fire is in place.
