The deadliest attack took place in the predominantly Shi'ite Muslim district of Bayaa when a bomb in a parked vehicle detonated near car workshops, killing seven and wounding 14, the sources said.

Violence in Iraq is at the highest level in at least five years and the capital has been targeted almost daily. More than 8,000 have been killed in 2013, the United Nations says.

Sunni insurgents, mostly with links to al Qaeda, have claimed several large bombings in Iraq this year.

Al-Qaeda has increased its grip on areas across the country since the escalation of the crisis in neighbouring Syria and the withdrawal of US troops from Iraq at the end of 2011.

At least 66 people were wounded in Sunday's attacks. In one, a car bomb exploded in a busy square in the city's centre, killing at least five people and wounding 15, police said.

In Radhwaniya, a predominantly Sunni area, a roadside bomb killed two people and wounded a further eight, police said.

There were other attacks in Baghdad's mainly Shi'ite districts of Amel and Ghadir.
