At least five people have been killed and more than 40 injured after a car bomb exploded in the Iraqi town of Tuz Khurmatu, 170km north of Baghdad, a police official said.
Women and children were among the casualties of Friday's bombing, Colonel Hussein al-Bayati said.
The attack severely damaged several surrounding houses as well as the home of Niazar Nomaroglu, a Turkmen councillor, al-Bayati added.
Reports suggest the target of the attack was Nomaroglu himself, who has been targeted before on at least two separate occasions.
According to reports, he was not in the area at the time of the attack.
Tuz Khurmatu is located in the province of Kirkuk, where Iraq's majority Arabs and minority Kurds are locked in a struggle over land, wealth and power.
Later on Friday, armed men in two cars attacked an army checkpoint in the Akashat area northwest of Baghdad near al-Qaim.
At least six soldiers were killed and four others wounded in the attack.
