The attack was carried out at the northern neighborhood of Rashidiya, where another car bomb attack had just occurred on Tuesday.
The Tuesday attack killed at least 25 people and injured dozens of others at a vegetable market in Rashidiyah.
Baghdad has seen a dramatic rise in such attacks over the past weeks, most of them claimed by the hardliner Daesh group.
No group has claimed responsibility for the two attacks in Rashidiya yet, however.
In a deadly attack on July 3, nearly 300 people lost their lives after a bomber detonated an explosives-rigged vehicle at a shopping district in the Iraqi capital’s Karrada neighborhood. Daesh claimed responsibility for that assault.
The fresh wave of violence in Baghdad prompted Iraqi Prime Minister Haider al-Abadi to sack a number of high-ranking officials responsible for security in the capital, including the head of the Baghdad Operations Command.
According to the United Nations Assistance Mission for Iraq, a total of 662 Iraqis were killed and another 1,457 wounded in acts of extremism, violence and armed conflict in June. A great portion of the fatalities was recorded in Baghdad, where 236 civilians were killed.
