The leaders of Serbia and Kosovo have tentatively agreed on how to implement a European Union-sponsored plan to normalize their relations after decades of tensions between the two Balkan wartime foes, EU foreign policy chief Josep Borrell said Saturday after chairing talks between them.

Speaking at a news conference after nearly 12 hours of talks in the North Macedonian lakeside resort of Ohrid, Borrell told reporters that Serbian President Aleksandar Vucic and Kosovo Prime Minister Albin Kurti " have reached an agreement on how to do it.”
