Following the cessation of the Kosovo war in June 1999 and the subsequent return of ethnic Albanians from abroad, approximately four fifths of Kosovo's pre-1999 RAE population had been expelled from their homes. Many Kosovo Albanians regarded the Roma as having collaborated with the Yugoslav Army. Roma were claimed to have assisted the Serbian police in plundering Albanian homes and shops to supply the military action, and in burying the Albanian dead. According to Roma accounts, the Yugoslav authorities coerced them into providing assistance. Many Roma were also recruited into the Yugoslav Army to "help terrorise Albanians" and Roma homes were marked with an "R" on their doors to distinguish them from Albanian houses when the Serbian paramilitaries arrived to plunder.
