Police in the northern Iraqi city of Mosul say a suicide car bombing has killed at least four people and wounded more than 50 others.
The huge blast occurred this (Sunday) morning outside a police station. Insurgents in Iraq often target police facilities.
Police in Baghdad say a roadside bomb exploded there today, killing a man and a woman. Two other people were hurt.
