The chief war crimes prosecutor for the United Nations, Carla del Ponte, said that the European Union should not proceed on negotiations with Serbia until all war crimes suspects have been arrested. Del Ponte has stated that, despite positive assessments by the EU, Serbia should not be perceived as meeting its full obligations to join the European community. Despite recent arrests of key suspects accused of war crimes during the 1992-95 conflict there, there are still several fugitives suspected of being harbored by sympathizers. Among the remaining fugitives are Ratko Mladic and Radovan Karadzic, key architects of the massacre in Srebrenica, where over 8,000 Muslim men and boys were slaughtered in 1995. “We don't have Karadzic and Mladic in custody ‚ that is a failure. If they are not arrested and tried by the tribunal that will be the biggest failure … of the international community,” Del Ponte said. Those watching this case suspect the two suspects will be handed over to the Hague this summer.
