It was the deadliest attack in the Iraqi capital this year.
Reports say the attacker was driving a truck carrying food when he detonated his explosives, destroying stores and market stalls in the mostly Shi'ite Sadriyah neighborhood.
In the northern city of Kirkuk today, a series of car bombings killed at least two people and wounded more than 30 others. Authorities imposed a nighttime curfew on the city following the attacks.
Authorities also imposed curfews on two other cities, Mosul and Samarra, after outbreaks of violence there as well.
