More than a dozen bomb attacks in and around Baghdad on Sunday left 16 people dead, including 10 people killed in a suicide attack, and more than 70 wounded.
The series of attacks comes just days after blasts against police in a northern city killed 29 people.
There are just months to go before all US forces must withdraw from Iraq.
A total of 12 roadside bombs, three vehicles packed with explosives and one suicide attacker struck in the spate of morning blasts.
The deadliest attack saw 10 people killed and 15 wounded in a suicide bombing in the town of Taji, 25 kilometres north of the capital.
Among the casualties were six police killed and 10 wounded.
