Iraqi officials say a car bomb at a busy bus station in the capital has killed at least nine people.
Authorities say 16 people were wounded in the attack Sunday in Baghdad.
The attack comes three days after a suicide bomber detonated his device among a group of security force recruits in Baghdad, killing nearly two dozen people.
Violence in Iraq has reached a level not seen since 2008, when the country was emerging from a period of brutal sectarian killings.
The United Nations says more than 8,000 people were killed in Iraq last year.
