Former Yugoslav leader Slobodan Milosevic has gone on trial in The Hague for alleged war crimes during the Balkan wars of the 1990s. Milosevic is charged by the United Nations war crimes tribunal in the Hague with crimes against humanity in Croatia and Kosovo, and genocide in Bosnia. It is the biggest European war crimes trial since Hitler's henchmen were tried at Nuremberg after World War II. The U.N.'s chief prosecutor accused former Yugoslav leader Slobodan Milosevic of being "responsible for the worst crimes known to humankind" at the opening of his landmark war crimes trial. "Some of the incidents revealed an almost medieval savagery and a calculated cruelty that went far beyond the bounds of legitimate warfare," Chief Prosecutor Carla Del Ponte said.
