A suicide bomber has attacked Shi'ite worshippers in eastern Baghdad, killing at least 11 people.
Police say the attack on August 25 on the Shi'ite place of worship also wounded at least 32.
The attack comes three days after suspected Shi'ite militiamen killed 70 Sunni worshippers at a mosque northeast of the capital.
The August 22 attack on the mosque in Imam Wais village near Baquba has raised sectarian tensions in Iraq as the Iraqi government is fighting to dislodge Islamic State militants from positions in the north of the country.
