Serbia may have its hopes for closer ties with the European Union dashed by poor marks by a United Nations war crimes report disclosed on Thursday, according to dpa. Serge Brammertz, chief prosecutor of the International Criminal Tribunal for the former Yugoslavia (ICTY), will tell the UN Security Council that Serbia is not doing enough to apprehend war crime suspects, TV B92 said, citing the report. Serbia's existing strategy for the arrest of fugitives has completely failed, B92 said, quoting from those portions of Brammertz's report it was allowed to see. Brammertz is due to address the Security Council on June 6. The report warns Serbia that it needs a "new, much more rigorous" approach to the search for fugitives, because without it "they will not be arrested." Serbia has been hard-pressed to arrest two remaining fugitives, Bosnian Serb Ratko Mladic and Croatian Serb Goran Hadzic. Mladic is charged with genocide in connection with the killing of 8,000 Muslims at Srebrenica in 1995. Hadzic faces charges of war crimes in connection with a Serb insurgency in Croatia between 1991 and 1995. Serbian leaders say they expect the EU to formally grant it the status of membership candidate this year.
