and 2007, when the country was teetering on the edge of civil war.

Most of Wednesday's attacks happened in within minutes of each other as people headed to work or were out shopping early in the day. Insurgents unleashed explosives-laden cars, suicide bombers and other bombs that targeted parking lots, outdoor markets and restaurants in predominantly Shiite areas in and around Baghdad, officials said. A military convoy was hit south of the capital.

Security forces sealed off the blast scenes as ambulances raced to pick up the wounded. The twisted wreckage of cars littered the pavement while cleaners and shop owners brushed away debris. At one restaurant, the floor was stained with blood and dishes were scattered on plastic tables.

"What sin have those innocent people committed?" asked Ahmed Jassim, whowitnessed one of the explosions in Baghdad's Hurriyah neighborhood. "We hold the government responsible."

The northern neighborhood of Kazimiyah, home to a prominent Shiite shrine, was among the worst hit. Two bombs went off in a parking lot, followed by a suicide car bomber who struck onlookers who had gathered at the scene. Police said the attack killed 10 people and wounded 27.

There was no immediate claim of responsibility for the attacks, but they bore the hallmarks of the Iraqi branch of al-Qaeda, which operates in Iraq under the name the Islamic State of Iraq and the Levant. The group frequently targets Shiites, which it considers heretics, and carries out coordinated bombings in an attempt to incite sectarian strife.
