The United States extradited Thursday to Bosnia a former Muslim prison guard accused to have abused Serb civilian detainees during the 1992-1995 war, prosecutor's office said. Almaz Nezirovic, one of rare Muslims to be indicted by Bosnia's prosecutors for war crimes, is suspected to have participated in "torture" of Serbs in a detention camp in the northern Bosnian region of Derventa between April and July 1992.
