An armed Shi'ite volunteer from the brigades of radical cleric Muqtada al-Sadr, takes his position during a military advance in areas under the control of militants of the Islamic State, formerly known as the Islamic State in Iraq and the Levant (ISIL), on the outskirts of Samarra July 12, 2014. Followers of al-Sadr, who fought U.S. troops under the banner of the Mehdi Army during the 2003-2011 occupation, have returned as Sadr's new "Peace Brigades." The black-turbaned cleric was shown on television this week surrounded by aides in camouflage poring over maps of deployments around Samarra. Picture taken July 12, 2014.
