Iraqi authorities say a suicide truck bomber has killed eight Shiite militiamen and wounded more than a dozen near a city north of Baghdad.
Police officials say the attack took place today afternoon when the bomber drove his explosives-laden truck into a checkpoint manned by Shiite militias near the city of Tikrit.
At least 15 Shiite fighters were also wounded in the attack.
Tikrit, which fell under the control of the Islamic State group last summer, is 130 kilometres (80 miles) north of Baghdad.
Medical officials confirmed the casualties. All officials spoke on condition of anonymity because they were not authorised to talk to the media.
No one immediately claimed responsibility for the explosion. Iraq sees near-daily bombings and other attacks mainly targeting the country's Shiite majority and security forces.
