t concentration of bodies in mass graves so far discovered in Kosovo since the end of the 11-week NATO bombing campaign. "There are reports that these sites contain 350 bodies," Major Jan Joosten said at a daily briefing for journalists with the KFOR peacekeeping force. "It‘s just a report," Joosten said afterwards, adding that KFOR was sealing off the site and would clear it of mines to facilitate work by the International Criminal Tribunal for former Yugoslavia (ICTY). Italian forces along with the International Criminal Tribunal for former Yugoslavia have been asked to investigate, Joosten said. The ICTY office in Pristina said no one who was authorised to speak for the tribunal was available. Spokesmen for the tribunal‘s office in the Hague were not immediately available for comment. Joosten said the reports had been received by KFOR on Thursday evening from the western zone controlled by Italian peacekeepers. He declined to elaborate on where the information had come from. "We get reports from all kinds of people," he said. One of the biggest sites discovered so far was at Bela Crkva, northwest of Prizren, where villagers on Monday buried 60 of 64 victims reported to have been shot dead by Serb security forces on March 25, hours after the NATO bombing of Yugoslavia began. The Bela Crkva site is one of six mass grave areas listed by the International War Crimes Tribunal in its indictment of Yugoslav President Slobodan Milosevic and four of his top associates for crimes against humanity.
