Mladic war crimes trial opens THE HAGUE, Netherlands, May 16 (UPI) -- Former Bosnian Serb military commander Ratko Mladic, known as the "Butcher of Bosnia," went on trial Wednesday for war crimes amid cries for justice. The International Criminal Tribunal for the former Yugoslavia, sitting in The Hague, Netherlands, heard a prosecutor list the atrocities allegedly committed by soldiers under Mladic's command as Bosnian Serb units carried out an ethnic cleansing during the Bosnian war in the 1990s and directed a reign of terror against the civilian population in Sarajevo, The New York Times reported. Among the counts listed in the indictment against Mladic was the siege of Sarajevo, a 44-month campaign of sniping and shelling in which more than 10,000 people died. Mladic is the last major player in the Bosnian conflict to face trial before the tribunal. Mladic, captured last May, faces two counts of genocide, one for the ethnic cleansing campaign and a second for a massacre of a small contingent of U.N. peacekeepers in Srebrenica. About 8,000 unarmed men and boys were slaughtered over a several-day period in July 1995 in what were portrayed as acts of vengeance for Serbian deaths at the hands of Muslims. "The prosecution will present evidence that will show beyond a reasonable doubt the hand of Mr. Mladic in each of these crimes," prosecutor Dermot Groome said. Mladic has said he isn't guilty of any wrongdoing and has refused to enter a formal plea. The court entered a not guilty plea on his behalf Wednesday. In the gallery, survivors from Bosnia hurled insults as Mladic appeared, the Times said. One woman shouted "vulture" as he looked over the crowd and gave a thumbs-up sign to an acquaintance. During a break, Kada Hotic, who traveled from Srebrenica, said: "He ordered the killing of my husband, my son, my two brothers and my brother-in-law. Now that I look him in the face; I want revenge. A woman whose parents were killed in the conflict said a war-crimes trial is too good for him. "I understand democracy, but exceptions need to be made when it comes to monsters," Delila Lacevic told the Los Angeles Times. If convicted, the "Butcher of Bosnia" could face a life sentence in a European prison. Those warlords include Bosnian Serb wartime political leader Radovan Karadzic, arrested in 2008 for alleged war crimes committed against Bosnian Muslims and Bosnian Croats during the Siege of Sarajevo, as well as ordering the Srebrenica massacre, and former Serbian President Slobodan Milosevic, arrested in 2001 for alleged war crimes and crimes against humanity in the wars in Bosnia, Croatia and Kosovo.
