The Komsomolska Pravda (from Russia) went to Kosovo to investigate the accusations that imprisoned Serbs were killed in order to sell their organs. They came back with a series of three articles. It is rather chilling to see how widely known the rumours were and how much little pieces of evidence they found.
I am curious whether any Western journalist will take up the subject and make a similar report. The HRW report on the subject can be found here.
Follow-up: on 9 july B92 had an article under the title "UNMIK covered up organ trafficking" that claims that an UNMIK official with the name Jose Pablo Baraybar was responsible for the subject and blocked further investigations.
