Donetsk, Ukraine (CNN) – Pro-Russia separatists in eastern Ukraine have decided to go ahead with a Sunday referendum on greater local powers, they said Thursday, defying a call by Russian President Vladimir Putin to postpone the vote.
Putin had urged the pro-Russia sympathizers to delay the referendum to give dialogue "the conditions it needs to have a chance."
Representatives from the council of the self-declared Donetsk People's Republic and separatists from Luhansk told reporters they have voted to press ahead to ask eastern Ukrainians there if they want sovereignty from Kiev.
