Iraq's maverick Shiite cleric Muqtada al-Sadr (back-C) takes part in Friday prayers in which Sunni and Shiite Muslim worshippers took part together in a gesture of unity at the Abdul Qadir Gilani Mosque in Baghdad on January 4, 2013, as protests in Sunni-majority areas across the country were planned to call for the release of prisoners and criticise Nuri al-Maliki's Shiite-led government.
