Shootings and bombings in Iraq has killed at least 21 people, as the country struggles with rampant violence ahead of parliamentary elections at the end of the month.
The country is suffering from a protracted surge in bloodshed that has killed more than 2500 people this year and sparked fears Iraq is slipping back into the all-out sectarian fighting of 2006-2007.
The unrest has been driven principally by complaints among the Sunni Arab minority of mistreatment by the Shiite-led government and security forces, and by the civil war in neighbouring Syria.
In Thursday's deadliest single incident, a car bomb exploded near a petrol station in the Ameen area of east Baghdad, killing at least seven people and wounding 35, officials said.
Another car bomb exploded in an area of shops in the capital's northern Shiite-majority Sadr City district, killing at least six people and wounding 18.
