Kosovo NPR's Sylvia Poggioli reports from Kosovo where the United States Special Envoy, Robert Gelbard, visited today. Gelbard told both the Serbian government and ethnic Albanians to stop what he called a "worrisome cycle of violence". The victims of last week's police crackdown still aren't buried. Serb police have threatened to dump the bodies a mass grave unless they're claimed by relatives. Those relatives want international forensic experts to examine the bodies first.
