A roadside bomb followed by a suicide bombing near a Shia mosque south of Baghdad killed at least six people and wounded 19 on Friday, security and medical officials said.
The first blast struck as worshippers were leaving Friday prayers, while the suicide bomber detonated explosives after security forces arrived.
Security forces members were among the dead and wounded, but the exact number was not immediately clear.
There was no immediate claim of responsibility for the attack, but Sunni extremists, including the self-styled Islamic State jihadist group, often carry out bombings targeting Shias, whom they consider heretics.
The bombings came a week after a series of attacks claimed by IS targeted Shias in Baghdad, killing at least 19 people.
