E/CN.4/1995/91 page 35 attacks by Muslim extremists, on 8 August 1993, 30 November 1993 and 22 March 1994. These repeated attacks seem to show that Pastor Williams has been targeted to be killed at all costs. Religious extremism is also reported to be manifest in schools, despite the directive of the Ministry of Education. In some schools, Christian and Muslim children have allegedly been separated and have no common activities. In others, Christians are said to be subjected to constant victimization and pressure. In March 1993, the two-week expulsion of four pupils from a secondary school for playing a cassette containing anti-Christian comments in class reportedly caused anti-Christian riots and petrol-bomb attacks on the local church, in which at least 52 Christians were injured. The public education curricula are also allegedly discriminatory in so far as Christian pupils are obliged to memorize verses of the Koran as part of their Arabic studies. The Copts also seem to be the object of discrimination regarding admission to the State medical schools. Similar discrimination is allegedly also found in public sector jobs such as the police, the army and other government institutions. The Coptic church is reportedly the object of discriminatory practices such as delays in the issue of permits to build or restore places of worship. The Government reportedly arbitrarily confiscated the land of a Coptic church for the use of the Ministry of Islamic Affairs. An Egyptian administrative court apparently decided in 1989 that this land should be returned to the Coptic church. However, this decision has not to date been acted on. The Special Rapporteur was also informed that, while freedom to change one’s religion was not explicitly condemned by law, article 98 f of the Penal Code was sometimes invoked in punishing the conversion of Muslims. This article prohibits any act which ’dishonours or shows contempt for a holy place or a religious sect with the intention of undermining national unity and public order’. Egyptian courts have reportedly upheld the principle that Muslims cannot change their identity document in order to record their conversion to another religion. As a result, married men who are no longer Muslims must register their children as Muslims. In addition, the pressures exerted by the family and society allegedly make it practically impossible for a Muslim to convert to another religion. Cases brought to the Rapporteur’s attention can be summarized as follows: in February 1993, four Christian foreigners are reported to have been detained for more than two months, and then expelled on 10 May 1993 for proselytizing Muslims; an Egyptian Christian, Abdul Hamid Adel Nafa, aged 25, who was arrested along with the four foreigners, was allegedly accused of proselytism but was not released. After being placed initially in the psychiatric ward of the Abasseya Hospital, Cairo, he has apparently been held in the Al Khana institution for the mentally ill since August 1993. In October 1992, Hanaan Rahman Assofti, aged 26, who had renounced Islam for Christianity, was allegedly arrested by State Security officers at Cairo Airport when leaving to meet her fiancé abroad.
