Abu Hamza al-Masri (أبو حمزة المصري Abū Ḥamzah al-Maṣriy) (15 April 1958) is an extremist Sunni Muslim who lives in the United Kingdom and is known for his preaching against non-Muslims.
Abu Hamza was born Mustafa Kamel Mustafa in Alexandria, Egypt, in 1958. He is the son of a middle class army officer. In 1979, he entered the UK on a student visa. He studied civil engineering at Brighton Polytechnic.
On May 16, 1980, he married Valerie Traverso (now Fleming), a Catholic convert to Islam, and had a son, Mohammed Mustafa Kamel. He acquired British citizenship following three years of marriage. In 1984, he divorced his wife, because she had failed to divorce her previous husband until 1982. The marriage was void. It is not known whether Abu Hamza was aware of this; if he was, his British citizenship could be invalidated.
