Iraqi officials say a series of explosions across Baghdad killed at least 30 people Tuesday, after a Sunday attack in the city left at least 57 people dead.
Investigators say at least 11 explosions rocked Baghdad neighborhoods late Tuesday. They say the blasts, a combination of roadside bombs and car bombs, wounded at least 70 people.
Authorities say most bombings have occurred in predominately Shi'ite areas. Some of the bombs have gone off near areas that include crowded markets and restaurants.
The attacks have taken place on the same day that hundreds of mourners gathered to pay last respects to the victims of Sunday's attack in a Catholic church in Baghdad.
Authorities say at least 57 people were killed and nearly 70 wounded after militants attacked the Our Lady of Salvation Church and took more than 100 people hostage Sunday. An al-Qaida-linked group, the Islamic State of Iraq, claimed responsibility.
The siege ended when Iraqi forces stormed the church hours later. It is not clear how many people were killed by the militants and how many died during the rescue attempt.
Iraqi officials on Tuesday announced the detention of a Baghdad police commander whose district included the church.
Tuesday's memorial service took place at another church near the attack site.
The Islamic State of Iraq has been demanding the release of fellow militants from prisons in Iraq and in Egypt, and has warned of more attacks against Christians.
France has offered asylum to 150 Iraqi Christians, including some who were wounded during Sunday's siege.
