Amnesty International is calling on the European Union to do more to investigate potential war crimes committed by both the Serbs and Albanians during the 1999 conflict in Kosovo.
Amnesty called on the EU to beef up its mission in Kosovo, EULEX, to make such a task a top priority, including more police, prosecutors and judges.
Amnesty also said more needed to be done to probe postwar crimes targeting Serbs, Roma and others.
Earlier this week, NATO Secretary General Anders Fogh Rasmussen told EU lawmakers that EULEX was underfunded and that NATO peacekeepers had to police volatile parts of Kosovo.
Nearly 13 years since NATO ousted Serb forces from Kosovo, the territory remains divided along ethnic lines.
