[JURIST] Carla del Ponte [UN profile], chief prosecutor for the International Criminal Tribunal for the former Yugoslavia [official website], on Thursday called for the EU to pressure Croatia and Serbia to take action on arresting suspects wanted by the UN tribunal and said the EU should not build closer ties with the countries until they do so. Del Ponte said it was "shameful" that the two most wanted fugitives, former Bosnian Serb wartime leader Radovan Karadzic [ICTY case backgrounder; Wikipedia profile] and his military commander Ratko Mladic [ICTY case backgrounder; Wikipedia profile], were still at large. The men are wanted in connection with the 1995 Srebrenica massacre [BBC timeline], which involved the genocide of 8,000 Muslims, as well as the 43-month siege of Sarajevo that killed 10,000. Del Ponte said that the EU should postpone talks with Belgrade, which is hoping to join the EU, until Mladic has been handed over, and should also not advance talks with Croatia until the country turns over Ante Gotovina, another wanted fugitive.
