Two policemen and a female bystander were killed when a suicider bomber blew himself up in a car near the Iraqi Kurdish city of Kirkuk , AFP reported on Monday.
The attack in Dibis northwest of Kirkuk  wounded around 100 people, many of them schoolchilren, a local official said, speaking to the news agency.
Iraqi Kurdistan has been hit by a number of attacks in recent months  as the security situation across the country deteriorates and the regional government continues to dispute oil contracts with Baghdad.
The blast on Monday morning targeted the police station but also struck the adjacent girls' secondary school. Attacks of the same nature have killed 220 people in Iraq in the last month , according to AFP's count, using security and medical sources.
