NATO bombing in March–June 1999 resulted in the damaging of the Gračanica Monastery, Patriarchal Monastery of Peć complex of four churches, as well as the Visoki Dečani and wall paintings of the Hermitage of St. Peter of Koriša, among the more notable churches. Cultural historian András Riedlmayer stated that no Serbian Orthodox churches or monasteries were damaged or destroyed by the KLA during the war. However, in the aftermath of war, KLA fighters were accused of vandalizing Devič monastery and terrorizing the staff. KFOR troops said KLA rebels vandalized centuries-old murals and paintings in the chapel and stole two cars and all the monastery's food. Karima Bennoune, United Nations special rapporteur in the field of cultural rights, referred to the many reports of widespread attacks against churches committed by the Kosovo Liberation Army. In 2014, John Clint Williamson announced EU Special Investigative Task Force's investigative findings and he indicated that a certain element of the KLA following the conclusion of the war (June 1999) intentionally targeted minority populations with acts of persecution that also included desecration and destruction of churches and other religious sites. Fabio Maniscalco, an Italian archaeologist, specialist about the protection of cultural property, described that KLA members seized icons and liturgical ornaments as they ransacked and that they proceeded to destroy Christian Orthodox churches and monasteries with mortar bombs after the arrival of KFOR.
