SARAJEVO, Bosnia-Herzegovina (AP) — Bosnian Serb authorities on Wednesday held an official commemoration for a top former wartime leader, despite his war crimes conviction by a U.N. court. The Bosnian Serb president, prime minister and other officials attended the event in the northern city of Banja Luka, the seat of the Serb-run part of Bosnia called Republika Srpska. The gathering illustrates the continued Bosnian Serb denial of their wartime leaders’ role in the atrocities committed against non-Serbs during the 1992-95 war in Bosnia.
