The men — Hussein Hasab, 21, and Haider Hassan, 43 — died of gunshot wounds Friday after thousands, mostly supporters of powerful Shiite cleric Muqtada al-Sadr, surged up to the walls of Baghdad's highly fortified Green Zone compound. On Friday, security forces fired tear gas and live ammunition at a crowd of mostly al-Sadr supporters when hundreds breached the compound and entered the Prime Minister's offices and Parliament. The Green Zone breach ratchets up the pressure on an Iraqi government that remains gridlocked amid the political crisis. Since the Green Zone was overrun last month, Parliament has been unable to convene. On Saturday, a suicide bombing in Dujail, 50 miles (80 kilometers) miles north of Baghdad targeting a government complex killed four and wounded 10, according to hospital and police officials.
