A car bombing on Monday evening in the Iraqi capital Baghdad killed at least 15 people and wounded 33, an interior ministry official told AFP.
The blast happened at around 7:00 pm (1600 GMT) in the busy business district of Hay al-Amel in the west of the city, he said.
There was no immediate claim of responsibility for the explosion, which bore all the hallmarks of a suicide attack by the Islamic State group.
The radical Sunni jihadist group is under assault in both Iraq—in the country’s second city Mosul which IS seized in June 2014 -- and in neighbouring Syria.
In that year, the jihadists took vast swathes of Iraqi territory north and west of the capital.
Iraqi government forces backed by the US-led international coalition have since retaken many cities, including Tikrit.
But as IS has lost ground in Iraq, it has also retained the ability to stage regular attacks there.
