A group calling itself the Islamic State of Iraq has said it was responsible for the twin truck blasts that rocked Baghdad Sunday. The Associated Press reports the explosions killed at least 155 people, including 24 children leaving a day care center.
The group, which is a coalition of militant Sunni groups including Al Qaeda, said its "martyrs...targeted the dens of infidelity" in a statement posted online Monday.
The blasts damaged the justice and public works ministries, as well as the Baghdad Provincial Council building.
The group's statement said, "one of these selected targets that were hit this time was the 'Ministry of Injustice and Oppression,'" referring to the Ministry of Justice.
This is not the first time the group has targeted government buildings. The AP reported the Islamic State of Iraq engineered blasts that killed 100 people near administration buildings in August.
"There's wicked political will behind these terrorists acts," Iraqi Prime Minister Nouri al-Maliki said in a speech at Baghdad University Monday. "We are facing big challenges in the reconstruction process, but while we are building, they are destroying."
