Kosovo and European Union police said Friday they had uncovered a mass grave in the east of the former Serbian province, according to dpa. The remains of at least eight people were discovered at the site, said the spokesman for the European Union's law enforcing mission in Kosovo, Christophe Lamfalussy. Forensic experts were now working at the grave, he told German news agency dpa. "We suspect they are victims from 1998," he said. The exhumation began Thursday and was expected to last until Sunday. Kosovo, with its 90-per cent ethnic-Albanian population, was the scene of a brutal guerrilla war between the Albanian insurgents and Serbian security forces and paramilitaries. Several high-ranking Serbian politicians and security officials, including the late Slobodan Milosevic, were put on trial by a United Nations war crimes tribunal for atrocities in Kosovo. NATO ended the conflict in 1999 by ousting Belgrade's forces from Kosovo, paving at the same time the way for the province's unilateral declaration of independence last year.
