Forensics experts have found more than 120 bodies of Muslims killed by Serbs in a mass grave in eastern Bosnia.
"The figures change from hour to hour but we expect to find 30 more," said Mr Murat Hurtic of the Commission for Missing Persons of Bosnia's Muslim-Croat federation.
The team had also found 70 incomplete bodies at a lower layer of the grave, Mr Hurtic reported from the site in a field at Bljecevo.
He said his team was struggling with very high temperatures and bodies literally in pieces, mixed with earth and plastic bags of the former Yugoslav Army.
"It's chaotic. We are working at three metres depth and the temperature in the grave reaches about 50 degrees Celsius," he said. "We can barely breath for the gases steaming out from the plastic bags."
The latest mass grave to be excavated is near the Potocari suburb of Srebrenica, scene of Europe's worst atrocity since World War Two in which 7,000 to 8,000 Muslim men and boys were slaughtered in a three-day massacre by the Bosnian Serb Army, under the command of General Ratko Mladic.
Mladic is wanted on charges of genocide by the United Nations war crimes tribunal in The Hague, along with his wartime boss, Bosnian Serb president Radovan Karadzic, who is also still at large.
Hundreds of mass graves have been found across Bosnia since the end of the 1992-95 war, in which some 200,000 people were killed, most of them Muslims, and two million fled their homes.
