Iraqi security officials say a suicide blast and a roadside bomb have targeted a Shi'ite mosque in a southern Baghdad neighborhood, killing 10 people.

Police officials say the attack happened in the Nahiyet al-Rasheed neighborhood where a roadside bomb went off first on the street outside the mosque, just as worshippers were finishing Friday prayers. Within minutes, a suicide bomber inside the mosque detonated an explosives vest.

The officials say 28 people were also wounded in the attack. Two police officers are among the dead and four have been wounded. The officials spoke on condition of anonymity because they are not authorized to talk to the media.

No one immediately claimed responsibility for the attack.

Baghdad sees near daily attacks, many claimed by the Sunni militant Islamic State group.
