FILE - In this Wednesday, September 18, 1996 file photo, six International War Crimes Tribunal Investigators clear away soil and debris from dozens of Srebrenica victims buried in a mass grave near the village of Pilica, approx 55kms (32 miles) north east of Tuzla, at a former pig farm. Ratko Mladic, the ruthless Bosnian Serb military leader charged with orchestrating the July 1995 slaughter of up to 8,000 Muslim men and boys in the Bosnian town of Srebrenica, which was supposed to be a safe zone guarded by Dutch peacekeepers, was arrested at a relative's home in a tiny Serbian village on Thursday May 26, 2011, after a 16-year hunt for the architect of what a war-crimes judge called "scenes from hell."
