According to official reports, protesters in Serbia say they will attempt to block the excavation of what they said may be a mass grave containing bodies of ethnic Albanians.

Serbian news outlet B92 reported on Monday that the Association of Families of Missing Serbs from Kosovo said they would try to halt the operation unless there was simultaneous investigation of alleged mass grave sites in Kosovo where Serbs are thought to be buried.

The excavation effort near the town of Raska would be blocked, Association Coordinator Milorad Trifunovic said, unless investigations into the Kosovo sites began.

He also said that the association wants exhumations to begin at Livacka Lake, Kosare and Belacevac.

Trifunovic further said that more than 1,700 Serbs and non-Albanians from Kosovo remain listed as missing. (With inputs from Agencies)
