According to a Serbian government report, from January 1, 1998 to June 10, 1999 the KLA killed 988 people and kidnapped 287; in the period from June 10, 1999 to November 11, 2001, when NATO took control in Kosovo, 847 were reported to have been killed and 1,154 kidnapped. This comprised both civilians and security force personnel: of those killed in the first period, 335 were civilians, 351 soldiers, 230 police and 72 were unidentified; by nationality, 87 of killed civilians were Serbs, 230 Albanians, and 18 of other nationalities.

According to Human Rights Watch, as "many as one thousand Serbs and Roma have been murdered or have gone missing since June 12, 1999."
