BAGHDAD - Nine Iraqis were killed and 17 wounded in attacks around the country on Monday, police and medics said, as insurgents continued to strike at Iraq's fledgling security forces.
Four people were killed and nine wounded when a suicide bomber rammed his car into two police vehicles at a roadside checkpoint early in the day in southwest Baghdad, an interior ministry official said.
Two of those killed were policemen burned to death in their vehicle.
Medics said six policemen and three civilians were wounded in the attack in Saydiyah district and taken to hospital for emergency treatment.
