The Iraqi Government locked down Baghdad on Sunday before this week's Arab League Summit, Reuters reports. Security checkpoints and roadblocks have been set up in a maze-like fashion, across the capital. The move comes in order to protect Baghdad from insurgent attacks and is part of an effort to show that the country has pulled away from years of violence just months after U.S. troops left the area. "We have to rely on these old-fashioned methods like blocking the streets," said Shi'ite Prime Minister Nuri al-Maliki. "So far it's been a success despite the impact on the citizens."
