Baghdad (CNN) -- Two civilians were killed and 35 people were wounded when a car bomb exploded in central oil-rich Iraqi city of Kirkuk on Wednesday morning, police said.
The car bomb exploded in a busy road that leads to Kirkuk municipality building and Kirkuk general hospital.
Seven police officers were among the wounded people who were in a police patrol parked on the side of the road.
Kirkuk, about 240 kilometers (150 miles) north of Baghdad, is an ethnically mixed city including Kurds, Turkmen and Arabs.
A number of outstanding issues in the province between Kurds and Arabs remain unsolved, including disputed territories and power-sharing among ethnic groups.
