Abu Musab al-Suri, born Mustafa bin Abd al-Qadir Setmariam Nasar (), is a suspected Al-Qaeda member and writer best known for his 1,600-page book "The Global Islamic Resistance Call" ("Da'wat al-muqawamah al-islamiyyah al-'alamiyyah"). He has held Spanish citizenship since the late 1980s following marriage to a Spanish woman. He is wanted in Spain for the 1985 El Descanso bombing, which killed eighteen people in a restaurant in Madrid, and (as a witness) in connection with the 2004 Madrid train bombings. He is considered by many as 'the most articulate exponent of the modern jihad and its most sophisticated strategist'.
