At least 25 civilians and members of government forces have been killed in northern Iraq since late Sunday in attacks by the Islamic State group, officials said.
The attacks came despite Baghdad's declaration of victory over the jihadist group late last year.
That attack took place on the outskirts of Amerli in the province of Kirkuk, about 200 kilometres from Baghdad.
In a separate attack, three people were killed while driving a car further north near the city of Daquq, said the officer, who spoke on condition of anonymity.
"The attackers then burned the car," he said.
Hamdi blamed IS, saying members of the jihadist group were hiding out in the surrounding desert and making incursions into populated areas.
The mayor of Mushirfa village and two of his children were killed in the attack on his home, Hamdi said, as well as two tribal fighters of the Hashed al-Shaabi paramilitary units that played a leading role in the fight against IS.
In mid-February, IS claimed responsibility for killing 27 people in the Hawija area of
Kirkuk province, also setting up a fake checkpoint and disguising themselves as soldiers.
It was the deadliest attack on Iraqi forces since they retook control last October of Hawija, the jihadists' last bastion in northern Iraq.
In December, Baghdad announced the "end of the war" against the IS and that government troops -- army, police and Hashed al-Shaabi -- were in control of the long and porous Iraqi-Syrian border.
Experts and officials, however, believe that jihadists hiding out in the desert still have the ability to strike and even to seize areas of Iraq, especially near the Syrian border.
