At least eight people have been killed and 15 wounded when a bomb in a car parked in Baghdad's eastern outskirts exploded, police and medics said.
It is the third deadly attack to strike Iraq's capital in a week.
It is the third deadly attack to strike Iraq's capital in a week.
The explosives-laden car was parked near an outdoor fruit and vegetable market, a police officer told Associated Press.
He said six civilians and two policemen were killed.
There was no immediate claim of responsibility for the attack in the predominately Shia Muslim neighbourhood of al-Obaidi but Islamic State regularly targets civilian areas in the heavily fortified capital.
Attacks across Baghdad in the past week, some claimed by the ultra-hardline Sunni group, have killed more than 60 people, with violence escalating as US-backed Iraqi forces try to drive the militants from the northern city of Mosul.
Violence has claimed the lives of at least 6,878 civilian Iraqis last year, the United Nations said on Monday.
