Ukrainian President Petro Poroshenko, speaking to reporters at the NATO summit , said the Ukrainian government and rebels will order the cessation of hostilities Friday on condition that an agreement is signed on a new peace deal that would end the five-month war in eastern Ukraine.
He said both sides have signed a preliminary protocol at the meeting in Belarus to start a ceasefire.
Alexander Zakharchenko, head of the self-proclaimed Donetsk People's Republic, the main separatist group, said in a statement his forces would also order a ceasefire after a peace plan is signed, Reuters reports.
A protocol on a 14-point peace will includes "all aspects of control and prisoner exchange," the Interfax-Ukraine news agency reports, quoting source close to the negotiations in Minsk.
