Insurgents killed 16 people in Iraq on Saturday, including 11 in Baghdad, where four bombs rocked the capital, security sources said.
Eight civilians were killed and 38 wounded when a car bomb and a roadside bomb exploded simultaneously in a market in central Baghdad's Hafidh al-Qadi area, a security source said.

Two more roadside bombs in Baghdad killed another two people dead and five wounded, the source said.
Gunmen shot dead an Iraqi intelligence officer in south Baghdad. Tahsin Ali Mahmud was ambushed as he was driving through Baya neighbourhood, the source said.
In another attack, gunmen killed a policeman and a woman in the city of Baquba, north-east of Baghdad, police said, adding that another civilian was similarly shot dead.
A policeman was also shot dead by gunmen near the Iranian border in the town of Zarbatiya, 80 kilometres (50 miles) south of the city of Kut, police said.
Interior Ministry spokesman Brigadier Abdul Karim Khalaf said that during the week ending Wednesday, 39 policemen were killed and 170 others wounded across Iraq.
