Ukraine has retracted an earlier claim to have reached a ceasefire with Russia. The office of Ukrainian President Petro Poroshenko initially said he agreed with Russian counterpart Vladimir Putin on steps toward a ceasefire with pro-Russian rebels in eastern Ukraine. But the Kremlin then denied a ceasefire agreement, saying it is not in a position to make a deal because it’s not a party to the fighting. Ukraine has accused Russia of direct involvement in the violence amidst a recent escalation. The confusion comes as President Obama visits the former Soviet Republic of Estonia ahead of a major NATO summit in Wales. More than 2,600 people have been killed in eastern Ukraine since April, the majority by Ukrainian forces. The United Nations says more than one million people have been displaced, over a quarter of them internally.
