Abdel Aziz Issa Abdul-Mohsin Al-Muqrin (/ˈɑːbdəl əˈziːz ˈɪsə ɑːlˈmɪɡrɪn/ ⓘ; Arabic: عبد العزيز عيسى عبد المحسن المقرن; also Abd al-Aziz al-Moqrin and other transliterations), alias Abu Hajr (ابو هاجر) and Abu Hazim, (1972 – 18 June 2004), was the leader of the militant Jihadist group al-Qaeda in Saudi Arabia.

[2] In 1995 he was arrested in Ethiopia and accused of taking part in a botched assassination attempt on Egyptian president, Hosni Mubarak.

"[5] Mohsen Al-Awaji, an expert in extremism, said in media interviews in 2004 that Al-Muqrin was "shallow, very simple-minded," adding that he "has no political brain.

"[citation needed] By contrast, Michael Scheuer, a former CIA intelligence officer, has described Muqrin as a strategist who wrote about insurgency doctrine.

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,[2] and the kidnapping and beheading of American contractor Paul Johnson.
