A spokesman for President Vladimir Putin on Wednesday denied Ukrainian reports Russia had brokered a "permanent cease-fire" in eastern Ukraine, news agency RIA Novosti reported.
Kremlin spokesman Dmitry Peskov was cited as saying Russia could not have reached such a deal with Ukraine's Petro Poroshenko because it is not a party to the Ukraine conflict.
"Putin and Poroshenko really discussed the steps that would contribute to a ceasefire between the militia and the Ukrainian forces. Russia cannot physically agree to a ceasefire because it is not a party to the conflict," Peskov said.
In an earlier statement, Poroshenko's press office said: "As a result of the conversation (between the Ukrainian president and Putin) agreement was reached on a permanent ceasefire in the Donbass.
"Mutual understanding was achieved concerning the steps which will enable the establishment of peace," it added.
