At least 70,000 troops -- most of them Iraqi -- were deploying Wednesday on the streets of Baghdad in an effort to bring security to the Iraqi capital, according to the Iraqi Interior Ministry. The additional security will include Iraqi police, police commandos, soldiers and emergency police as well as U.S.-led coalition forces, the ministry said. The forces will secure checkpoints on Baghdad's roads as well as enforce a 9 p.m. to 6 a.m. curfew. There also will be a ban on civilians carrying weapons. The forces will wear new uniforms to distinguish them from insurgents, who often wear police or military outfits to carry out attacks. Officials said it's the largest operation in Baghdad since the U.S. turnover to Iraqis in June 2004. Despite the crackdown, a car bomb targeting an Iraqi army patrol in Baghdad on Wednesday killed two people and wounded 10 others, police told CNN. The incident took place in the Qahira neighborhood of northern Baghdad.
