BELGRADE, Serbia - No bodies have been found at a site that was suspected to be a mass grave in southern Serbia, a judge said Friday after investigators searched for three days for remains of victims of the 1998-99 Kosovo war.

"We found no human remains," said Milan Dilparic of the Belgrade-based Special Court handling war crimes cases, including atrocities committed during the Kosovo fighting between Serb government troops and Kosovo's ethnic Albanian separatists.

Thousands of ethnic Albanians and hundreds of Serbs perished in the fighting, which ended with NATO military intervention that forced a Serb pullout from the disputed province in 1999.

Some 800 bodies of ethnic Albanians were found after the conflict in two mass graves in central Serbia - an attempt by former Serbian leader, Slobodan Milosevic, to cover up the crimes.

The latest site investigated was an abandoned quarry in a border zone between Kosovo province, currently a U.N. protectorate, and the rest of Serbia. The investigation was prompted by reports that more than 350 Kosovo Albanians were buried there.

Witnesses had reported having seen four trucks unload bodies in the area of Raska, 100 miles south of Belgrade.
