Numerous war crimes were committed by all sides during the Kosovo War, which lasted from 28 February 1998 until 11 June 1999. According to Human Rights Watch, the vast majority of abuses were attributable to the government of Slobodan Milošević, mainly perpetrated by the Serbian police, the Yugoslav army, and Serb paramilitary units. During the war, regime forces killed between 7,000–9,000 Kosovar Albanians, engaged in countless acts of rape, destroyed entire villages, and displaced nearly one million people. The Kosovo Liberation Army has also been implicated in atrocities, such as kidnappings and summary executions of civilians. Moreover, the NATO bombing campaign has been harshly criticized by human rights organizations and the Serbian government for causing roughly 500 civilian casualties.
