Russian President Vladimir Putin on Tuesday asked the upper chamber of parliament to revoke a resolution allowing him to send troops into Ukraine, as pro-federalization activists agreed to to a truce and talks on ending the current crisis.

"In the aim of normalizing the atmosphere and resolving the situation in the eastern regions of Ukraine and also in connection with the start of three-way negotiations on this issue a request was sent to the Federation Council to cancel the resolution," Russian news agencies quoted Kremlin spokesman Dmitry Peskov as saying.

Russian senators granted Putin the right to send the army into Ukraine on March 1 following the ouster in Kiev of pro-Moscow president Viktor Yanukovych, arguing that Russian speakers in the country are threatened.

The deputy head of the Federation Council's foreign affairs committee Andrei Klimov told Interfax that lawmakers in the rubber stamp chamber would back the proposal to withdraw the authorization for military intervention at a vote Wednesday.

The de-escalation comes as pro-federalization activists in eastern Ukraine agreed to a temporary ceasefire and talks with the new Western-backed president, following support for the peace initiative from Putin.

The prominent head of the self-declared Donetsk People's Republic on Monday reversed his firm rejection of President Petro Poroshenko's peace overtures by agreeing to a ceasefire that would last until Friday morning.

"We hope that during the period in which both sides halt fire, we will be able to agree and begin consultations about holding negotiations about a peaceful settlement to the conflict," Oleksandr Borodai said after a meeting with Russia's ambassador to Kiev and an OSCE envoy.
