Four bombs exploded in central Baghdad on Wednesday, killing at least 33 people.
Two were car bombs opposite the foreign ministry in the Iraqi capital on the edge of the Green Zone, home to parliament and the US embassy.
In another incident, a suicide bomber in a car detonated himself outside a restaurant close to a checkpoint one street away from the Green Zone.
The fourth explosion was near Khullani Square in central Baghdad
No group immediately claimed responsibility.
The bombings, which wounded dozens more, came as security forces battled Sunni fighters in the western Anbar province, where two cities were taken over by al Qaeda on 1 January.
More than 1000 people were killed across the country last month.
