At least four people were injured Thursday in a car bombing north of the Iraqi capital Baghdad, police said, a day after eight were killed in three separate attacks, dpa reported.
The latest attack was carried out by a suicide bomber who blew himself up inside the car at a market in Tikrit, some 170 kilometres north of Baghdad, added the officials.
At least 33 people were killed Tuesday in bomb attacks in the cities of Karbala and Diwaniya, south of Baghdad.
