BAGHDAD (AP) -- Iraqi officials say a suicide bomber who walked into a Shiite mosque in northern Baghdad has killed 15 worshippers and wounded 32.
The attack happened on Friday night during prayers in Baghdad's Kiraiyat neighborhood.
A police officer and a medical official both confirmed the casualties. Both spoke on condition of anonymity as they were not authorized to talk to the media.
A car bombing earlier in the day killed four civilians and wounded six north of the Iraqi capital.
Since December, members of Iraq's Sunni minority have been staging demonstrations over what they call second-class treatment by the Shiite-led government. In some places, clashes erupted between security forces and protesters.
The deadliest incident was in the northern town of Hawija in April, where 23 people were killed.
