There have been reports of war crimes committed by the KLA both during and after the conflict. These have been directed against Serbs, other ethnic minorities (primarily the
Roma) and against ethnic Albanians accused of collaborating with Serb authorities. According to a 2001 report by
Human Rights Watch (HRW):
The KLA was responsible for serious abuses… including abductions and murders of Serbs and ethnic Albanians considered collaborators with the state. Elements of the KLA are also responsible for post-conflict attacks on Serbs, Roma, and other non-Albanians, as well as ethnic Albanian political rivals... widespread and systematic burning and looting of homes belonging to Serbs, Roma, and other minorities and the destruction of Orthodox churches and monasteries... combined with harassment and intimidation designed to force people from their homes and communities... elements of the KLA are clearly responsible for many of these crimes.
