On 19 June 1992, the war in Bosnia broke out, though the Siege of Sarajevo had already begun in April after Bosnia and Herzegovina had declared independence. The conflict, typified by the years-long Sarajevo siege and the Srebrenica massacre, was by far the bloodiest and most widely covered of the Yugoslav wars. The Bosnian Serb faction led by ultra-nationalist Radovan Karadžić promised independence for all Serb areas of Bosnia from the majority-Bosniak government of Bosnia. To link the disjointed parts of territories populated by Serbs and areas claimed by Serbs, Karadžić pursued an agenda of systematic ethnic cleansing primarily against Bosnians through massacre and forced removal of Bosniak populations. Prijedor ethnic cleansing, Višegrad massacres, Foča ethnic cleansing, Doboj massacre, Zvornik massacre, siege of Goražde and others were reported.
