Russia says it has resolved a dispute over sending aid to rebel-held cities in eastern Ukraine, but talks on a ceasefire remain at an impasse. The Russian government says it will send a convoy of nearly 300 trucks carrying food, water and medicine with help from the International Committee of the Red Cross. But negotiations over an end to the fighting are continuing after a meeting in Berlin failed to yield an agreement. The United Nations says the death toll from the violence in eastern Ukraine has doubled in recent weeks to more than 2,000 since mid-April.
