The surprise announcement from the head of the self-proclaimed Donetsk People's Republic came a day after Russian President Vladimir Putin publicly threw his weight behind Kiev's peace overtures and urged the separatists to halt fire.
Ukraine's security services confirmed today evening that militia strikes in the two heavily Russified industrial regions that have been at the heart of the insurgency came to an abrupt halt in the late afternoon.
"In response to the ceasefire declared by Kiev, we pledge to also halt fire on our part. This ceasefire will last until June 27," Oleksandr Borodai told Russia's ITAR-TASS news agency in Donetsk.
"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," he told Russian state television in separate comments.
The news delivered a desperately needed boost to Poroshenko two weeks into a presidency that is scrambling to stamp out both a deadly uprising and an economic meltdown that has been compounded by a cut in Russian gas deliveries last week.
Poroshenko has been pressing world leaders to follow through with their threat to unleash devastating economic sanctions against Russia should Putin fail to immediately end his perceived military and diplomatic backing for the insurgency.
The new Kiev leader will also sign a historic EU trade pact on Friday that crowns his May 25 election promise to make the decisive move westward -- one strongly resisted by Russia and that lies at the heart of the current crisis.
