Muqtada al-Sadr Hojatoleslam Sayyid Muqtada al-Sadr (مقتدى الصدر Muqtadā aṣ-Ṣadr) (b. August 12, 1973) is the fourth son of the famous Iraqi Shi‘a cleric, the late Grand Ayatollah Mohammad Mohammad Sadeq al-Sadr and son-in-law of Grand Ayatollah Mohammad Baqir As-Sadr. As of early 2004, he was the de facto ruler of the Sadr City section of Baghdad and commanded the loyalty of the Mahdi Army, an Iranian-backed insurgent force making a bid for power in Iraq.[1] Clashes with U.S. forces in April were followed by a truce in June, and mixed signals from al-Sadr after his promises to disband his militia and become involved in the political process. The Coalition Provisional Authority had on several occasions threatened to arrest al-Sadr, and in early April 2004 issued an arrest warrant, alleging his involvement in a homicide. U.S. military commanders expressed an intention to "capture or kill" him. - Now he is a constant menace in Iraqs government.
