 Around 3 April, Serb forces removed the bodies of those massacred in anticipation of the arrival of a Bosnian government delegation tasked with investigating what had transpired. A number of sources put the figure of civilians killed in the hundreds or possibly a thousand, but the International Criminal Tribunal for the former Yugoslavia (ICTY) and the Serbian War Crimes Prosecutor's Office were only able to verify between 48 and 78 deaths. Post-war investigations have documented the deaths of a little over 250 civilian of all ethnicities in the Bijeljina municipality during the course of the war. After the massacre, a campaign of mass ethnic cleansing of non-Serbs was carried out, all mosques were demolished, and nine detention camps were established. Many deaths in Bijeljina were not officially listed as civilian war victims and their death certificates claim they "died of natural causes."
