Bosnia's Foreign Minister Mladen Ivanic quit on Saturday, saying his party would refuse to bow to international pressure and enact police and defence reforms. Ivanic's move came as no suprise after Bosnian Serb Prime Minister and party colleague Dragan Mikerevic resigned on Friday to protest what they said were moves against the Serb Republic's constitution by top peace overseer Paddy Ashdown. "We do not want to take part in a process that would lead to creation of Bosnia without the Serb Republic. This is an attack on us and it is a direct consequence of our opposition to unconstitutional changes," Ivanic told a news conference. Ashdown fired nine Bosnian Serb officials on Thursday to punish the Serb Republic for its failure to arrest war crimes fugitives, thus blocking the Balkan country's admission in the NATO Partnership for Peace (PfP) programme for non-members.
