Iraq Interior Ministry officials said the incident happened in Tal Afar at an outdoor market, CNN reported. They said the bomber purposely collided with another vehicle and began arguing with its driver, detonating his bomb as a crowd gathered around the shouting men.

Officials told CNN the bombing happened in the same marketplace where another car bombing left more than 24 people dead last month.

Elsewhere in Iraq, four people were killed in two separate roadside blasts, one in Baquba, the capital of Diyala province north of Baghdad, and another south of the same city, CNN reported.

Military sources also said 10 Iraqis were injured in three explosions hitting different areas of Baghdad, the Kuwait News Agency, KUNA, reported.

A bomb was detonated near Al-Shaab International Stadium and Al-Qadsiya swimming pool injuring four Iraqis, the news agency said. Another bomb injured three policemen and a third explosion in the Zafaraniya neighborhood in southern Baghdad injuring three policemen after their patrol was also targeted.
