Every spring, Kosovo commemorates the 1998-99 war. Most of the war crimes and massacres happened between March and June of 1999, when NATO bombed Kosovo for 78 days to end the repression and ethnic cleansing of Kosovo Albanians by the Serbian regime. NATO still has troops here as part of its longest peacekeeping operation in history. During the war, multiple burials and exhumations were conducted by the Serbian forces, aiming to cover up traces of war crimes. Today there are close to 1,650 ethnic Albanians, Serbs, Roma, Ashkali and Egyptians still missing and in some cases, graves for those whose remains were brought back from mass graves over the last two decades were reopened when new body parts were identified by the forensics team headed by the Forensics Institute at the European Union Rule of Law Mission in Kosovo (EULEX) and Kosovo's Department of Forensic Medicine. An estimated 20,000 women and men were raped by Serbian forces during the war. Shame and stigma prevent survivors from publicly talking about what happened to them. Because of this national silence and a weak justice system, not a single perpetrator has been sentenced to prison for rape.
