The Kosovo Force (KFOR) is a North Atlantic Treaty Organisation-led international peacekeeping force which was responsible for establishing a secure environment in Kosovo. KFOR entered Kosovo on 12 June 1999, two days after the adoption of UN Security Council Resolution 1244. At the time, Kosovo was facing a grave humanitarian crisis, with military forces from the Federal Republic of Yugoslavia (FRY) and the Kosovo Liberation Army (KLA) in daily engagement. According to NATO, Serb forces had committed ethnic cleansing of Kosovo Albanians and the death toll had reached a historic high. Nearly one million people had fled Kosovo as refugees. KFOR has gradually transferred responsibilities to the Kosovo Police and other local authorities. As of 23 May 2016, KFOR consists of 4,600 troops.
