At least 13 people have been killed and 33 injured in a car bombing in a Shiite-dominated neighbourhood in southern Baghdad, security sources and witnesses told dpa.
The car, which was parked in a busy shopping street, exploded late Monday in the area of al-Amel in the Iraqi capital, sources added.
Ambulances rushed to the scene, carrying those injured to nearby hospitals.
The extremist Islamic State claimed responsibility for the attack, which it said killed 21 people.
The statement could not be verified by dpa.
The radical Islamic State militia has been behind the deadliest attacks in the city, including a car bombing that killed 45 people in February.
The radical Sunni Islamic State, which regards Shiites as heretics, often targets markets, restaurants and other crowded locations in mainly Shiite districts, as well as Shiite religious ceremonies.
Iraq is currently engaged in a US-backed military campaign aimed at driving Islamic State from its key stronghold of Mosul, the country's second-largest city.
Troops are currently engaged in an operation to dislodge the Islamic State fighters from western Mosul and have been moving north, closer to the old city centre. They forced the extremists out of the eastern side of the city almost a month ago.
