Serb authorities early Saturday handed over an ex-Bosnian Serb police chief wanted by the Yugoslav war crimes tribunal. A Belgrade court rejected an appeal by Stojan Zupljanin on Friday against his extradition. The U.N. tribunal has charged Zupljanin with war crimes for allegedly overseeing Serb-run prison camps where thousands of Muslims and Croats were killed during the 1992-95 war in Bosnia, according to a report of the Associated Press. He was arrested in the town of Pancevo last week after nine years on the run. Zupljanin is the 43rd Serb suspect extradited to the international tribunal in The Hague, Netherlands. The others include the late former President Slobodan Milosevic, who is blamed for fomenting the wars in former Yugoslavia in the 1990s. Three other suspects remain at large. They are former Bosnian Serb political leader Radovan Karadzic, his military commander Gen. Ratko Mladic, and Goran Hadzic, a Croatian Serb leader. Karadzic and Mladic are wanted on genocide charges for allegedly organizing the 1995 massacre of 8,000 Muslims in Srebrenica and other atrocities of the Bosnian war. The EU has stressed that all the suspects must be arrested and extradited if Belgrade wants to move closer to the 27-nation bloc.
