Russian President Vladimir Putin supports the unilateral ceasefire declared on Friday by his Ukrainian counterpart, Petro Poroshenko, and the latter's declared desire to achieve peace in eastern Ukraine, the Russian leader's office said on Saturday.
However, "without practical action to launch a negotiation process, the proposed plan will not be viable or realistic," the office said.
"Putin believes that it is an unacceptable situation that, after the ceasefire order, ammunition comes flying from Ukraine onto Russian territory as a result of the ongoing conflict and explodes there, not only causing property damage but also endangering the life and health of our fellow citizens," it said.
"Poroshenko's declared peace plan must not be an ultimatum to the militias. The opportunity that is being offered by the cessation of hostilities must be used for constructive negotiations and for political compromises between the parties to the conflict in eastern Ukraine," the office said.
Putin urged the parties to the conflict to stop fighting and start talks, it said.
