Bosnian forensic experts have started exhuming the human remains from a recently uncovered mass grave believed to contain victims of the 1995 Srebrenica massacre, the war crime prosecutor's office said Wednesday. "So far remains of at least 15 victims have been recovered," the prosecutor said in a statement. The mass grave was uncovered at Kozluk, a village some 70 kilometres (40 miles) north of Srebrenica.
