Thousands are expected to gather Sunday at Potocari memorial in Srebrenica to mark the 15th anniversary of the Srebrenica massacre and pay respects to 775 victims whose remains were recently identified, dpa rported.
Serb forces, led by General Ratko Mladic, overran the Muslim enclave which was under the protection of UN peacekeepers and executed some 8,000 men and boys over a 10-day period in July 1995.
Some 10,000 people, including leading politicians from the Balkan region, are expected to attend the funeral.
The remains will be buried along those of 3,749 others previously identified.
The bodies of many more Srebrenica victims are still awaiting identification. Their remains are mainly partial, as the bodies of massacre victims were buried and reburied to try and to hide the crime.
Mladic, wanted by the UN war crime tribunal in the Hague, is still on the run and is thought to be hiding in Serbia. Serbian President Boris Tadic, who will attend the funeral, said his visit to Srebrenica was "an act of reconciliation and building bridges between people."
A column of some 5,000 people who are on a symbolic "march of peace" from Tuzla to Srebrenica, are due to arrive in time for the burial.
