The U.N. war crimes tribunal in The Hague could work beyond 2010, when it is due to close, if it has not brought to justice the top fugitives from the Balkan wars of the 1990s, the court's President Theodor Meron pledged. The International Criminal Tribunal for former Yugoslavia (ICTY) is supposed to wind up by the end of 2010. Around 110 people have stood trial so far, with at least 65 awaiting trial and 17 still at large. Its most wanted suspects, Bosnian Serb wartime leader Radovan Karadzic and his military chief Ratko Mladic, have evaded capture for 10 years. Both are indicted for the Srebrenica massacre and the 43-month siege of Sarajevo. "Let me say here, loud and clear, that the tribunal will not close its doors before we have tried Karadzic, Mladic and Gotovina," Meron said in a spontaneous aside to a speech in Sarajevo on Wednesday.
