Car bomb blasts, including a suicide attack, in two Shiite neighbourhoods of Baghdad killed at least 16 people Thursday, police and medical sources said.

Two car bombs near the frequently targeted district of Kadhimiyah killed at least nine, while a suicide car bomb attack in Talbiya killed seven, a senior Baghdad police official said.

The double car bomb attack, in a neighbourhood called Dolai, also wounded 25 people. All the victims were civilians, said a hospital source who confirmed the casualty figures.

The bombing in Talbiya, near the sprawling northern neighbourhood of Sadr City, left at least 23 wounded.

The United Nations said more than 1,110 people were killed in acts of violence across Iraq in September. According to an AFP count, around 400 have already been killed this month.

While the bloodshed has been mainly on the frontlines where federal, Kurdish and allied forces are battling the Islamic State jihadist group, blasts and executions in Baghdad continue to take a heavy toll.
