During this time, Serbs living in Croatian towns, especially those near the front lines, were subjected to various forms of discrimination from being fired from jobs to having bombs planted under their cars or houses. The UNHCR reported that in the Serb-controlled portions of the UNPA's, human rights abuses against Croats and non-Serbs were persistent. Some of the Krajina Serb "authorities" continued to be among the most egregious perpetrators of human rights abuses against the residual non-Serb population, as well as Serbs not in agreement with nationalistic policy. Human rights violations included killings, disappearances, beatings, harassment, forced resettlement, or exile, designed to ensure Serbian dominance of the areas. In 1993, the UNHCR also reported a continued series of abuse against Serbs in Croatian government-held areas which included killings, disappearances, physical abuse, illegal detention, harassment and destruction of property.
