Crackdown not immediately apparent in Baghdad

A security crackdown involving 75,000 Iraqi and US troops to deploy across the strife-prone capital was not immediately apparent in central Baghdad on Wednesday, where only a few new police checkpoints had been set up. As dawn broke over the Iraqi capital, home to about 6 million people, a few checkpoints had been added to those already functioning. It was not immediately clear if others had gone up in Baghdad or its outskirts. Security officials said 75,000 Iraqi and multinational forces would be deployed throughout Baghdad on Wednesday, securing roads in and out of the city, establishing more checkpoints, launching raids against insurgent hideouts and calling in airstrikes if necessary.
