A car bomb has exploded killing ten people near a police station in the northern Iraqi city of Kirkuk, police say.
A police official said the attack had been carried out by a suicide bomber driving a car in the Kurdish section of Kirkuk.
The attack was part of a relentless campaign of bombings of Iraqi police, whom guerrillas see as cooperating with US occupation troops.
It came at a time when Iraq's Kurds are pressing for greater autonomy ahead of a US handover of power to Iraqis on June 30th.
Ethnic tensions are running high in oil-rich Kirkuk between Kurds, Arabs and Turkmen who have attacked each other in a bid to gain influence over the city.
