Nima Khadum, a government employee, said the blasts shattered the windows of his Sadr City house. He said the air was heavy with smoke, while burning cars littered the street and the bodies of the dead and wounded lay nearby.
"The scene was a bloody one that brought to my mind the painful memories of the violent past," he said. "I don't see the benefit of security checkpoints that only cause traffic jams and don't do anything to secure Baghdad. The government, with its failing security forces, bears full responsibility for the bloodshed today."
Simultaneous explosions also hit the southeastern Baghdad neighborhood of al-Amin, where the force of the blasts left behind little except the mangled chassis of two cars.
An open-air market in Husseiniya, just northeast of the capital, and the Kamaliya area in Baghdad's eastern suburbs were also hit.
