Iraqi officials say a car bomb explosion in the northern city of Kirkuk has killed at least two people and wounded more than 20 others.
Investigators say the bombing Wednesday occurred near a hospital and government building.
Tensions have been high in the ethnically divided region, where Kurds and Arabs have been feuding for control.
On Friday, at least 20 people were wounded in a car bombing in the city.
Overall, violence has declined in Iraq from the height of sectarian conflict several years ago. However, militants still carry out attacks almost daily.
Some information for this report was provided by AP, AFP and Reuters.
