Bosnia's Serb Republic on Thursday pushed ahead with separatist reforms in violation of the country's constitution, and its pro-Russian leader Milorad Dodik publicly goaded state prosecutors one day after they issued a warrant for his arrest.

Bosnian prosecutors have ordered the detention of three top Bosnian Serb officials over a series of separatist actions in recent weeks that have heightened tensions in the Balkan country.

Bosnian officials on Thursday challenged a set of laws barring the state judiciary and police from operating in the Serb-controlled part of the country. The complaint filed at the country’s Constitutional Court jointly by Bosnian presidency member Denis Becirovic and two other officials argues that the laws passed a week ago by Bosnian Serb lawmakers violate Bosnia's constitutions and a peace agreement that ended Bosnia's 1992-95 war.
