Some people from non-Albanian communities such as the Serbs and Romani fled Kosovo, some fearing revenge attacks by armed people and returning refugees and others were pressured by the KLA and armed gangs to leave. The Yugoslav Red Cross had estimated a total of 30,000 refugees and internally displaced persons (IDPs) from Kosovo, most of whom were Serb.

In 2011, he was identified in leaked Western military intelligence reports as a "big fish" in Kosovan organized crime. He was President of Kosovo since 7 April 2016 until his resignation on 5 November 2020. On 24 June 2020 the Kosovo Specialist Chambers and Specialist Prosecutor's Office filed a ten-count Indictment, charging Hashim Thaçi and others for crimes against humanity and war crimes. Agim Çeku, the KLA's military chief, became Prime Minister of Kosovo after the war. The move caused some controversy in Serbia, as
