Iraqi civilians and security forces inspect a crater caused by a car bomb attack in Kirkuk.
A suicide car bomber joined by other suicide attackers on foot assaulted a provincial police headquarters in a disputed northern Iraqi city on Sunday, killing at least 15 people and wounding 90 others, officials said.
The blast in Kirkuk appeared to be a fresh attack by militants seeking to undermine government efforts in maintaining security nationwide.
A police officer said the car bomber drove his vehicle into the Kirkuk headquarters, followed by suicide attackers on foot armed with machine guns and grenades.
He said police killed all the militants before they could enter the building. The police officer did not specify how many attackers there were in total.
The officer spoke on condition of anonymity as he was not authorised to release information. The head of the provincial health directorate, Sidiq Omar Rasool, confirmed the casualty figures.
