U.S. General Louis Weber, commander of some 150 NATO troops in Bosnia, said that NATO does not know the whereabouts of the two most wanted Bosnian Serb war crimes suspects, Radovan Karadzic and Ratko Mladic the daily Dnevni avaz reported Tuesday, according to DPA. "NATO does not know where (former Bosnian Serb leader) Radovan Karadzic and (his army commander general) Ratko Mladic are," he told the paper "We have no information where they are." But he vowed that NATO would not give up and would continue searching for the two most wanted fugitives. The main responsibility, however, was on the authorities of Bosnia-Herzegovina and other countries in the region, Weber added. The fact that Karadzic and Mladic remain at large, he said, is hindering Bosnia's further progress. The Hague-based International Criminal Tribunal for the former Yugoslavia (ICTY) has indicted both Karadzic and Mladic for war crimes, genocide, crimes against humanity and severe breaches of the Geneva Conventions during the 1992-1995 war in Bosnia-Herzegovina. Both Karadzic and Mladic have been at large since the indictment was raised in July 1995.
