BAGHDAD, Dec. 27 (Xinhua) -- The Al-Qaida militant group in Iraq Tuesday claimed responsibility for a spate of deadly bomb attacks across Baghdad on Thursday that killed and wounded hundreds of Iraqis.
The self-styled Islamic State of Iraq (ISI), al-Qaida front in the country, said in a statement posted on an Islamic website that its attacks were meant to support the Sunnis in the prisons of the Shiite-dominated government and revenge to the Sunni prisoners who were executed by the government.
The statement said the attacks targeted security headquarters and military patrols, including a suicide car bombing outside the governorate of the criminal investigation near the building of the Iraqi Integrity Commission in Baghdad's central district of Karradah.
The statement threatened that Thursday was only one of these days that the Shiite government will witness soon.
The authenticity of the statement could not be verified immediately.
On Thursday a slew of deadly bomb attacks ripped across Baghdad in the morning and killed a total of 63 people and wounding 185, few days after the withdrawal of U.S. forces from the country.
The deadliest attack occurred in Karradah district in central Baghdad, when a powerful blast went off outside the building of the Integrity Commission, killing 23 people and wounding 46 others.
The attacks came amid growing struggle between Prime Minister Nuri al-Maliki's leading Shiite bloc and his political rivals, as the U.S. troops concluded their withdrawal plan few days ago, leaving less than 200 personnel in the country on training mission.
