A/CONF.189/PC.1/7 page 30 (f) In the United States, the Afro-American organization “Nation of Islam” is considered by both Muslim and Jewish leaders to be an extremist group within the American Muslim community and a source of intolerance purveying messages of hatred for whites, Catholics, Jews, Arabs, women, etc. (E/CN.4/1999/58/Add.1, para. 39).120 (b) Discrimination between variants within ethnic and religious minorities or groups 113. This hypothesis can concern ethnic and religious groups or minorities that are in principle different, but within which ethnic or even religious variations mark out subgroups. A second variant may be found in a country where there is a religious majority, but the population is so ethnically mixed that it is difficult to distinguish clearly between religious and ethnic conflicts. This category applies to many African States (see, for example, E/CN.4/1995/91, paras. 57-58). 114. In Ethiopia, the epitome of the multi-ethnic society (95 registered ethnic groups), in addition to the rivalry between Christians and Muslims (40 per cent of the population), tensions between the Protestant and Orthodox churches have been noted by the Special Rapporteur (ibid., para. 55). In Viet Nam, discrimination involving ethnic and religious minorities (more than 53 ethnic groups) or internal communities within these minorities have been noted by the Special Rapporteur (against the Buddhist Church, the Cao Dai Church,121 the Roman Catholic Church) (ibid., para. 100). In this context, it is important to note in particular the restrictions and discrimination suffered by the Khmer Krom community: these are the descendants of the Khmers of the Angkor civilization, Buddhist by religion but of Indian origin (E/CN.4/1999/58/Add.2, paras. 44, 68 and 118). (c) Discrimination involving minorities which are ethnically homogenous but define themselves in religious terms 115. Situations arising as a result of war, ethnic claims or “ethno-centric” nationalist movements are conducive to discrimination of this kind. In the Balkans, for example, the collapse of the State gave rise to micro-States that have been incapable of overcoming the ethnic and religious rivalries between the “constituent nations or peoples” and the other nations and minorities. In these countries, there is an ethnic dimension to religion, and religion may even become a “nationality”. Multiple identities become intertwined and people are “nationals” to varying degrees, despite the constitutional guarantee of non-discrimination. 116. In Croatia, Serbs and other minorities are reported to be suffering from harassment, looting and many forms of discrimination, in particular as regards the application of the law and criteria for recognizing Croatian nationality.122 In Bosnia and Herzegovina, refugees belonging to minorities suffer intimidation and violence and their homes are being destroyed, in order to discourage their voluntary return.123 In Kosovo, the gross violations of human rights suffered by ethnic Albanians (torture, deaths in detention, summary executions, widespread destruction of homes, property and villages, mass forced displacement, mass destruction of identity documents, etc.) can be compared to the crime of genocide and have been condemned in several international instruments.124 The presence in Kosovo of KFOR, an international force, has not prevented the resurgence of inter-ethnic conflicts between the Serb and Albanian communities, notably in the town of Mitrovica in February 2000, further complicating the search for a political solution in Kosovo.
