In Eastern Bosnia , Bosnian Serbs besieged the town of Srebrenica , among others . Srebrenica was declared a UN ' Safe Area ' in 1993 and it served as an enclave for Muslim refugees for the final years of the Bosnian War . In the middle of July 1995 , more than 8,000 Muslim Bosniaks , mainly men and boys , in and around the town of Srebrenica , were killed in what became known as the Srebrenica massacre , which was subsequently designated as an act of genocide by the International Criminal Tribunal for the former Yugoslavia and the International Court of Justice . The number of Croats was reduced by 135,386 ( the majority of the pre-war population ) , and the number of Bosniaks by some 434,144 . Some 136,000 of approximately 496,000 Bosniak refugees forced to flee the territory of what is now Republika Srpska have since returned home
