Serbian police say they are searching the house of a war crimes fugitive sought by a U.N. tribunal, AP reported. Police are inside the house belonging to the family of former Croatian Serb leader Goran Hadzic in the northern Serbian city of Novi Sad. Government official Rasim Ljajic says police are also searching the house of Hadzic's sister and the office of his brother in law. Hadzic is sought by the court in The Hague, Netherlands, for war crimes he allegedly committed as the leader of rebel Serbs in Croatia during the 1991-95 war in the republic. Hadzic is one of two Balkan suspects still at large. The other is the former Bosnian Serb army commander Ratko Mladic who is wanted on for genocide during Bosnia's 1992-95 war.
