Russia says crisis talks have ended between President Vladimir Putin and the leaders of France and Germany on a peace proposal for Ukraine.

A spokesman for Putin, speaking early Saturday, described the late-night talks as constructive, but did not provide details. Dmitri Peskov said the meeting will be followed by phone talks on Sunday between the Russian leader and Ukraine's President Petro Poroshenko, as well as further contacts with German Chancellor Angela Merkel and French President Francois Hollande.

Friday's meeting comes a day after the German and French leaders met in Kyiv with Ukraine's Western-backed president, Petro Poroshenko.

Ahead of Friday's meeting, Merkel said the initiative that she and Hollande are presenting in Moscow is aimed at defending "European peace" and ending the bloodshed in Ukraine.

"We are convinced that there will be no military solution to this conflict. But we also know that the question remains fully open whether we will succeed in achieving a ceasefire through these talks," Merkel said. "We do not know if we will be successful today or if perhaps further talks will be necessary. ... We can only do what it is in our power to do the situation is fluid and try to contribute all we can to a solution to this conflict, and particularly to bringing the bloodshed to an end.''

Hollande on Thursday called the proposal "a new solution to the conflict, based on the territorial integrity of Ukraine." Poroshenko said the plan "raised hopes" for a cease-fire.
