The explosion came just three weeks after a suicide car bombing in the capital targeted buses carrying military personnel, killing 29 people.
A Kurdish militant group which is an offshoot of the outlawed Kurdish rebel group, the Kurdistan Workers' Party, or PKK, claimed responsibility for that attack.
Police sealed off the area and pushed onlookers and journalists back, warning there could be a second bomb.
