According to Amnesty International Eritrea is one of the world's most repressive countries. In recent years, there have been increasing measures to prevent worshipers from practicing their faith. Some of the most prosecuted are Jehovah's Witnesses, and members of Evangelical congregations. The Eritrean government has shut down their churches, and persecuted many members of the congregations. After independence, President Issias Afwerki’s administration denied all basic rights to Jehovah's Witnesses. No members could receive any government assistance, or use any government services. Jehovah's Witnesses are not allowed to obtain national identification cards, without which they are not allowed to participate in the political and social sphere of Eritrea. National identification cards permit citizens to participate in everyday life, as well as in transactions with the government or any financial institution. The government began to informally allow Jehovah's Witness members to practice their faith within their home. They were still barred from practicing in any public space. Many families fled the country to seek asylum abroad due to mass persecution and imprisonment. According to Amnesty International, there are currently 250 families that have left Eritrea to seek asylum abroad. Domestic and international human rights organizations are not allowed to function in Eritrea. The registered, census-based religions are the Eritrean Orthodox Tewahedo Church (a miaphysite Oriental Orthodox denomination), the Roman Catholic Church, Eritrean Lutheran Church, and Sunni Islam. All other religions are persecuted, including other denominations of Islam, such as Shi'ism, and other denominations of Christianity, such as any of the myriad Protestant denominations (other than the Eritrean Lutheran Church) and Jehovah's Witnesses. All denominations of Christianity were given freedom of worship until 2002 when the government outlawed worship and assembly outside the 'registered' denominations. Evangelical churches in Eritrea have been some of the most persecuted religious groups. For religious groups to participate and freely practice their faith they must apply for registration with the Department of Religious Affairs. The government has seized many churches and religious buildings.
