A series of evening car bombs targeting commercial neighbourhoods of the Iraqi capital Baghdad killed at least eight people on Saturday, security and medical officials said.
The four blasts also left dozens more wounded, the latest in a months-long surge in bloodshed that has hit the country with less than two months left before national parliamentary elections.
The attacks, all car bombs against markets or commercial shopping areas of the Sadr City, Amil, Amin and Qahira neighbourhoods, killed eight people in all, according to police and medical sources who spoke on condition of anonymity.
More than 30 people were wounded, the sources said.
And a gun attack on the outskirts of the confessionally mixed city of Baquba left a mother and her son dead.
More than 230 people have been killed already this month, according to an AFP tally.
Iraq is grappling with its worst prolonged period of violence since it emerged from a bloody sectarian war that left tens of thousands dead in 2006-07.
Analysts and diplomats have urged the country's Shiite-led government to reach out to the Sunni community, who allege they are mistreated by the government and security forces.
But with elections looming on April 30, political leaders have been loath to be seen to compromise.
