Iraqi forces fire tear gas, bullets in air at Green Zone protesters: sources

BAGHDAD (Reuters) - Iraqi security forces fired tear gas and bullets into the air in an effort to stop more supporters of Shi'ite Muslim cleric Moqtada al-Sadr from entering Baghdad's fortified Green Zone, sources in the police and Sadr's office said on Saturday. SWAT troops and presidential guard forces were trying to keep the protesters from crossing a bridge close to the U.S. embassy compound, the Sadrist source said. Hundreds of the cleric's followers stormed into the Green Zone earlier and entered parliament after he denounced politicians' failure to reform a political quota system blamed for rampant corruption.
