Two separate car bomb attacks in northern Iraq killed six persons and wounded 18 on Tuesday, police officials reported.
In one attack in city of Tikrit in the northern Salahaddin province, a car bomb targeting a police patrol killed two civilians and wounded 12 persons, police officer Abdullah Qatan told the Voices of Iraq (VOI) news agency.
He said that of those wounded, four were police and the rest were civilians, reported dpa.
In the second attack, a car exploded at the Salahaddin provincial health center, killing four people, including two security men, police officer Hassan Ahmed told Deutsche Presse-Agentur dpa.
Six people were injured in the blast as a preliminary casualty count, Ahmed added.
The attack was possibly aimed at the center's director Hassan Zein al-Abdin who is also a member of the Supreme Islamic Council. He apparently was not at the centre at the time of the attack.
Police cordoned off the explosion area and investigations are still underway.
