Former Bosnian Serb leader Radovan Karadzic was transferred to a U.N. jail cell Wednesday to await trial on charges of waging a genocidal war against non-Serbs during the Balkan wars of the 1990s, the Associated Press reported. His arrival in a white Serbian government business jet from Belgrade marked the end of a 13-year effort by the Yugoslav war crimes tribunal to take custody of its most wanted war criminal, accused of responsibility for the deaths of tens of thousands of people and the sufferings of hundreds of thousands of Bosnian Muslims and Croats. Tribunal spokeswoman Nerma Jelacic, confirming his arrival at the U.N. detention center outside The Hague, said the tribunal will «ensure his well being and right to a fair trial as much as possible and in accordance with the highest international standards. » He was expected to be summoned before a judge within a few days and asked to enter a plea on each of 11 counts, including genocide, extermination and persecution.
