SREBRENICA, Bosnia-Herzegovina — In a first for Serbia, police on Wednesday arrested eight men accused of taking part in killing more than 1,000 Bosnian Muslims in the 1995 Srebrenica massacre, The Associated Press has learned. The move could be a significant milestone toward healing the wounds of Europe’s worst slaughter of civilians since World War II. Chief Serbian War Crimes Prosecutor Vladimir Vukcevic told the AP that all those arrested “are former members of a special brigade of the Bosnian Serb police.” The massacre took place at a warehouse on the outskirts of Srebrenica, a team of Serbian and Bosnian prosecutors told the AP.
