Three killed by Iraq bomb blast
Three people have been killed and 18 others injured in a car bombing in a northern Iraqi city rife with ethnic tensions, a police spokesman said.
Kirkuk city police spokesman Sarhat Qadir said the car was parked near a hospital and government office when it exploded at around 9am on Wednesday.
He said the attack appeared to be aimed at the city's Kurdish director of water and sewage.
Government officials are frequently targeted by insurgents looking to disrupt Iraq's shaky security.
Kurds and Arabs have been feuding over control of Kirkuk for years. Kirkuk is an ethnically mixed, oil-rich city that is located 180 miles north of the capital, Baghdad.
