Though it is the Balkans where anything’s possible, it sure sounds like horseshit to me—it has all the Big Lie characteristics of Jewish blood libel. Carla Del Ponte has gotten a deservedly bad reputation for her highly politicized and self-aggrandizing style, so the source of the story doesn’t add confidence. Regardless, I do hope there’s a proper investigation carried out so that this kind of stuff can be verified one way or another—there’s already enough rumor and mythology poisoning the air in the benighted Balkans.
