Milosevic: Parliament is continuing debate on a draft extradition law

Exhumations have already begun at the site, in the grounds of a police training school at Batajnica, only 10km (six miles) from the centre of the capital.

Officials had earlier accused former President Slobodan Milosevic of ordering the destruction of evidence of crimes.

A bitter row has broken out between the police and army over who was responsible for the atrocities.

Film

Exhumations of the mass grave began two weeks ago but have only just been made public.

The interior ministry released a ten-minute film showing human bones and skulls being removed from the ground.

No final figure has yet been released of the number of bodies found but they are believed to include those of 86 Kosovo Albanians originally put in a freezer compartment of a lorry and dumped in the River Danube.

Police sources say more such mass graves exist.

At least 4,000 Kosovo Albanians are still missing and their relatives had hoped to find them still alive in prisons in Serbia.

Evidence

The Serbian public has been shocked by the first real evidence of mass killings of Kosovo Albanians.

Former President Slobodan Milosevic, currently in jail awaiting trial on fraud charges in Belgrade, has been accused of ordering the disposal of evidence of massacres at a meeting in March 1999.

And, as more evidence of atrocities emerges, the public is becoming more sympathetic to demands for him to be extradited to face war crimes charges at the international tribunal in The Hague.

On Thursday, the Yugoslav parliament is due to resume debate on a draft law that would allow Mr Milosevic's extradition.
