Grand Ayatollah Ali al-Sistani, the highest Shi'ite religious authority in Iraq, reemphasized calls to political parties to pass electoral reform laws and respond to the protesters' demands. His comments were carried in his weekly sermon. The clashes centered on Baghdad's Rasheed Street -- a century-old avenue that was once the heart of Baghdad's cultural scene and is now known for its crumbling old buildings -- are the most intense altercations in recent days amid Iraq's massive weeks-long anti-government protests. The fighting appeared to have begun when protesters tried Thursday to dismantle a security forces barricade on the street, which leads to Ahrar Bridge, a span over the Tigris River that has been a repeated flashpoint. Security forces responded with barrages of tear gas and live ammunition that killed 10 protesters and injured more than 100 by Thursday evening. .
