11 people have been killed in a gun attack 70km from the northern Iraqi city of Kirkuk.
The men were ambushed while driving to work at an electricity station near Hawija, southwest of the volatile city of Kirkuk.
Police said it appeared the gunmen first stopped the electricity workers' vehicle and then opened fire on the men inside.
Seven of the men died instantly while four others were fatally wounded and died later in hospital.
It was not clear whether the attack was linked to an ambush in the same area on Saturday, when gunmen shot dead eight civilian employees of an Iraqi military base.
Four brothers were among the dead in that incident.
