Radovan Karadzic is to appear for the first time before a UN court in The Hague Thursday, facing charges that the former Bosnian Serb leader committed genocide and war crimes against Muslims and Croats during the 1992-95 Bosnia war, reported DPA. The session at the International Criminal Tribunal for the former Yugoslavia (ICTY) is scheduled to start at 4 pm (1400 GMT). It marks the first time Karadzic will appear in public since he disappeared in the aftermath of the Balkan war. Karadzic was arrested on a Belgrade bus by Serbian authorities on July 21 and transferred to the Netherlands early Wednesday. He has since been at the UN detention centre in Scheveningen, near The Hague.
