Bosnian Serb Prime Minister Milorad Dodik and top Bosnian Muslim leader Haris Silajdzic failed to reach compromise on key issues, including the reform of the constitution and the unification of Bosnia's ethnically divided police forces.
Both issues are holdovers from the Dayton peace treaty that ended the 1992-95 war by dividing Bosnia into two autonomous regions, the Republika Srpska and the Muslim-Croat Federation.
