Iraqi police say a suicide car bomber struck a Shi'ite district in Baghdad Thursday, killing at least 11 people and wounding more than 20 others.

The attack comes a day after a wave of bombings in mostly Shi'ite areas of the Iraqi capital killed 190 people and wounded more than 200 others .

Iraqi Prime Minister Nouri al-Maliki condemned Wednesday's carnage, calling the attackers "soldiers of satan." He also ordered the arrest of an Iraqi army colonel in charge of security of the Sadriyah market area, which was the site of the deadliest attack.

U.S. Defense Secretary Robert Gates called the bombings "horrifying," but said the attacks would have no effect on U.S.-led efforts to improve security in Baghdad.

Speaking in Israel Wednesday, Gates also called on states in the region to help stabilize Iraq, saying chaos there would hurt every country in the Middle East.

U.S. military officials say they suspect the bombings were the work of al-Qaida in Iraq terrorists and their Sunni insurgent allies trying to inflame sectarian passion.

The wave of attacks took place as Prime Minister Maliki announced that the Iraqi government planned to take full control of the country's security by the end of the year.
