Al-Muqrin was born to middle-class parents in Riyadh and was a high school dropout. He married at the age of 19 and had one daughter. He left his wife in about 1988 to fight the
Soviets in Afghanistan and later
fought in Bosnia-Herzegovina. In the 1990s he ran guns from Spain to Algeria. Most of his training occurred in jihadist camps in Afghanistan. He was reported to have fought against Ethiopian forces in the
Ogaden. Muqrin wrote a book on military strategy called
A Practical Course for Guerrilla War, which has been compared with Abu Bakr Naji's
Management of Savagery as a book that has influenced Al Qaeda's thinking on guerrilla warfare. Al-Muqrin was No. 1 on
Saudi Arabia's second official list of most wanted terrorists, which was published in December 2003. In 2004 his faction claimed responsibility for a series of attacks against Westerners in Saudi Arabia including the June 2004 shooting that seriously wounded BBC correspondent
Frank Gardner and killed cameraman Simon Cumbers, Al-Muqrin was responsible for the May 29
attacks at Al-Khobar that left more than 20 people dead and several other operations. The online magazine
Al-Khansaa claims to have been founded by al-Muqrin shortly before his death. In 2004, plans were discovered posted online under al-Muqrin's name containing the itinerary, routes of travel, and security personnel of Prince
Nayef bin Abdel Aziz, and plans to assassinate him with
RPGs. == Militant Activity (1988–2000) ==
