International officials have not furnished any evidence whatsoever that Radovan Karadjic and Ratko Mladic, the former leaders of Bosnian Serbs whom The Hague Tribunal accuses of war crimes, are taking shelter in Serbia, Serb Premier Zoran Djindjic said Wednesday. That was his reaction to US War Crimes Envoy Pierre-Richard Prosper's statement in which he said, the day before, that Yugoslavia would get financial aid on condition it proved it was not sheltering Messrs Karadjic and Mladic. The Serb premier, however, believes it is up to those who make the above assertions to prove them. Mr Djindjic said he had not received any reports whatsoever on the former military leaders' whereabouts in Yugoslavia over the past few months. What Belgrade has to deal with are groundless assertions which cannot make the authorities act, according to the premier. If someone reported their whereabouts and presented some evidence, it would make a difference, added the premier.
