Iraqi officials say a double-suicide bombing at a Shi'ite mosque in Baghdad killed at least 29 people and wounded 52 others.
Tuesday's coordinated blasts struck after midday prayers in the Iraqi capital's northern al-Qahira district. The first bomber detonated his charge at a checkpoint near the mosque and minutes later a second person blew himself up inside the building.
Iraq has seen a surge in violence that officials blame on Sunni Islamist insurgents and al-Qaida's affiliate in Iraq. The increase has raised concern about a return to widespread sectarian violence.
