Many of the civilian population of the occupied areas fled during the offensive or immediately after its completion, in what was later described in various terms ranging from expulsion to planned evacuation. Krajina Serb sources (Documents of HQ of Civilian Protection of RSK, Supreme Council of Defense published by Kovačević, Sekulić, and Vrcelj) confirm that the evacuation of Serbs was organized and planned beforehand. According to Amnesty International, "some 200,000 Croatian Serbs, including the entire Croatian Serb Army, fled to the neighbouring Federal Republic of Yugoslavia and areas of Bosnia and Herzegovina under Bosnian Serb control. In the aftermath of the operations members of the Croatian Army and police murdered, tortured, and forcibly expelled Croatian Serb civilians who had remained in the area as well as members of the withdrawing Croatian Serb armed forces". The ICTY, on the other hand, concluded that only about 20,000 people were deported. The BBC noted 200,000 Serb refugees at one point. Croatian refugees exiled in 1991 were finally allowed to return to their homes. In 1996 alone, about 85,000 displaced Croats returned to the former Krajina and western Slavonia, according to the estimates of the U.S. Committee for Refugees and Immigrants.
