At least four people have been killed and 38 wounded in car bombings in Kurdish areas of northern Iraq.
Officials say three car bombs exploded in two Kurdish areas in the violence-plagued city of Kirkuk, including one near an office of the Kurdistan Democratic Party.
Members of the Kurdish security forces were among the casualties.
More casualties were reported in roadside bomb attacks in the Sunni-dominated town of Hawija, west of Kirkuk, and in the majority Turkoman town of Tuz Khurmatu, south of Kirkuk.
No one has claimed responsibility for the attacks.
Kirkuk is home to a mix of Arabs, Kurds, and Turkomans, who all have competing claims to the oil-rich area.
