After several months of relative calm, the Iraqi capital was rocked by simultaneous bombings that left many dead and wounded.
The first attack took place in the morning rush hour, on a Baghdad street lined with restaurants and shops that are popular stopping points for breakfast.
A minibus full of schoolgirls was badly damaged by the car bomb. Several children and women were reported to be among the dead.
A number of other children were caught in the attack as many were on their way to school.
As onlookers gathered to help the victims, a suicide bomber ran into the crowd and detonated an explosives belt.
The attack took place in the mainly Shia district of Kasra, raising fears that it was aimed at stoking sectarian tensions.
No-one has claimed responsibility, but such attacks in Shia areas have been the hallmark of al-Qaeda in Iraq.
There was also violence in Baquba, north of Baghdad, where a female suicide bomber reportedly blew herself up and killed six at a checkpoint.
