A Shiite Muslim man holds a poster with images of anti-American Shiite cleric Moqtada al-Sadr (L), Imam Ali the cousin of the Prophet Mohammed, and the father of Moqtada, Ayatollah Mohammed Sadeq al-Sadr (R) as he listens to the Friday noon prayers in Baghdad's Sadr City neighborhood, on May 9 2008. Gun battles between Shiite fighters loyal to Moqtada and US forces in Baghdad's militia bastion of Sadr City overnight killed four people and wounded 51 others, Iraqi security and medical officials said. Since March 25th when the fighting began in this impoverished neighborhood, hundreds of people have died. AFP PHOTO / AHMAD AL-RUBAYE (Photo credit should read AHMAD AL-RUBAYE/AFP via Getty Images)
