U.N. investigators have dug up 2,108 bodies from mass graves in Kosovo and expect to find thousands of more victims of Serbian ethnic cleansing, the chief war-crimes prosecutor said last night.

In a grim report to the U.N. Security Council, Carla del Ponte said the exhumed bodies have come from 195 grave sites examined by forensic teams.

Del Ponte said she has reports that there are 529 mass-grave sites throughout Kosovo thought to contain a total of 4,266 bodies.

The staggering findings appear to confirm reports from refugees and NATO officials earlier this year about the scale of atrocities committed against the ethnic Albanian population by Serbian military and paramilitary forces during the Kosovo conflict.

And they are expected to lead to a series of new genocide indictments against Serbian strongman Slobodan Milosevic and his cronies and top generals.

NATO estimated that a total of 10,000 people were slaughtered in the Serbian ethnic-cleansing crackdown, but Del Ponte thinks the number of known dead will probably rise to more than 11,000.

The Swiss prosecutor said the numbers she is using do not reflect the total number of victims “because we have discovered evidence of tampering with graves.”

But a second report, meanwhile, made clear that the ethnic killing did not stop once NATO forces entered Kosovo.

NATO officials reported that 379 people have been murdered since the allied forces entered Kosovo in June – 135 Serbs, 145 ethnic Albanians and the rest Gypsies and members of other ethnic groups.

NATO officials said the homicide rate is cause for concern and a sign that revenge attacks between ethnic groups is continuing.
