Many persons continue to be detained in prisons for religious reasons and are in some cases subjected to torture and ill-treatment. Members of the clergy and believers of many denominations are subjected to death threats, intimidation, expulsion or enforced indoctrination. Some have been killed as a result of their religious activities. 94. However, the information gathered attests to the continued interest in problems of this nature on the part of the international community and reflects genuine efforts on the part of many Governments to restrict intolerance and discrimination and penalize violations in this domain. The Special Rapporteur would particularly welcome the continued dialogue, ir. & spirit of increasing cc—operation, between himself and all those Governments who so far have not been able to fully clarify ail concerns which he had occasion to bring to their attention. 95. The Special Rapporteur was most gratified to note the radical changes in the enjoyment of the rights and freedoms of thought, conscience, religion or belief that have taken place in Eastern Europe. The progress achieved in certain countries is particularly encouraging and the Special Rapporteur hopes that it will contribute to the strengthening of religious freedom in the region as a whole. The Special Rapporteur awaits with interest the announced changes in the constitutions of some countries of the region and intends to attentively follow their practical results. 96.

On the basis of incidents reported in the course of the past year, the Special Rapporteur has noted the persistent use of violence or threat of its use in dealing with problems of a religious nature. He has also taken note of the lack of activity of security forces in situations where their intervention might have been called for as well as the disturbing reports that, in some cases, they have taken part in repression based on religious intolerance. This can be the result of governmental practices that are at odds with both national and international legislation on the matter as well as the result of economic, social, political and cultural factors prevailing in the country. The Special Rapporteur has again noted how difficult it is to overcome the deep distrust opposing members of certain denominations as well as to eradicate extremist and fanatical opinions.
