Rohingya Christians in refugee camps in Bangladesh. Chad In Chad, Christians form a minority, at 41% of the population. They have faced an increasing level of persecution from local officials as well as Islamist groups like Boko Haram and tribal herdsmen. Persecution includes burning of Christian villages, closing of markets and killings. Egypt Foreign missionaries are allowed in the country if they restrict their activities to social improvements and refrain from proselytizing. Particularly in Upper Egypt, the rise of extremist Islamist groups such as the Gama'at Islamiya during the 1980s was accompanied by increased attacks on Copts and increased attacks on Coptic Orthodox churches; since then, the decline of those attacks has coincided with the decline of those organizations, but attacks still occur. The police have been accused of siding with the attackers in some of these cases. Since the 1980s, periodic acts of violence have been committed against Christians, and they include attacks on Coptic Orthodox churches in Alexandria in April 2006, and sectarian violence in Dahshur in July 2012. From 2011 to 2013, more than 150 kidnappings, for ransom, of Christians had been reported in the Minya governorate. Christians have also been convicted for "contempt of religion", such as poet Fatima Naoot in 2016. Indonesia In Indonesia, religious conflicts have typically occurred in Western New Guinea, Maluku (particularly Ambon), and Sulawesi. The presence of Muslims in these traditionally Christian regions is in part a result of the transmigrasi program of population re-distribution. Conflicts have often occurred because of the aims of radical Islamist organizations such as Jemaah Islamiah or Laskar Jihad to impose Sharia. In January 1999, towards the end of the East Timor genocide, tens of thousands died when Muslim gunmen terrorized Christians who had voted for independence in East Timor. In December 2011, a church in Bogor, West Java, was ordered to halt its activities by the local mayor. Another Catholic church had been built there in 2005. Previously a Christian church, GKI Taman Yasmin, had been sealed. Local authorities refused to lift a ban on the activities of the church, despite an order from the Supreme Court of Indonesia. Local authorities have persecuted the Christian church for three years. While the state has ordered religious toleration, it has not enforced these orders. In Aceh Province, the only province in Indonesia with autonomous Islamic Shari'a Law, 20 churches built in the 1930s and 1940s in Singkil
