At least 11 people have been killed after a suicide bomber attacked a security checkpoint in northern Baghdad.

The bomber on foot detonated his explosive vest near the entrance to Kadhimiya, a Shi'ite Muslim district killing at least eight civilians and three policemen, a police official said. He added that at least 32 other people were injured.

Medical sources in Kadhimiya hospital, where the victims of the bombing were taken, said the death toll could rise as some of the injured are in a serious condition, Reuters reported.

In a statement released by Amaq news agency, the Islamic State (Isis) claimed responsibility for the attack. The suicide bomber wearing a vest targeted security forces in the entrance to Kadhimiya neighbourhood.

Earlier this month, at least 292 people were killed in Baghdad when the group detonated two car bombs in a busy shopping area in the mostly Shi'ite Karrada district.
