The Coptic Church has grown in recent years in Libya, due to the growing immigration of Egyptian Copts to Libya. There are an estimated 40,000 Roman Catholics in Libya who are served by two Bishops, one in Tripoli (serving the Italian community) and one in Benghazi (serving the Maltese community). There is also a small Anglican community, made up mostly of African immigrant workers in Tripoli; it is part of the Anglican Diocese of Egypt. People have been arrested on suspicion of being Christian missionaries, as proselytising is illegal. Christians have also faced the threat of violence from radical Islamists in some parts of the country, with a well-publicised video released by the Islamic State of Iraq and the Levant in February 2015 depicting the mass beheading of Christian Copts.
