At least two civilians were killed and 12 people wounded, three of them policemen, when two car bombs exploded close to an Iraqi police patrol in eastern Baghdad on Wednesday (October 11), police and interior Ministry source said. The attack took place in al-Waziriya neighbourhood of eastern Baghdad. "Two car bombs exploded near the Ministry of Labour and Social Affairs. The target were civilians," said Ghassan Mutashar, an Iraqi policeman. Earlier, a bomb exploded near Iraqi army convoy in the western Baghdad neighbourhood of al-Mansour. Police said there were no casualties. In a separate attack in al-Mansour neighbourhood, another bomb exploded close to an Iraqi police patrol wounding one policeman. Meanwhile in central Baghdad, dozens of Iraqi prisoners were released at a major Baghdad bus station early on Wednesday. A source at the Ministry of Justice said it was a goodwill gesture to mark the Muslim holy month of Ramadan. Most of the prisoners were released from Abu Ghraib prison. Abu Ghraib became notorious for the images of U.S. soldiers mocking, physically abusing and torturing Iraqi prisoners that emerged last year. U.S. military officials and Iraqi authorities have since been at pains to show Abu Ghraib was now being run as a model prison.
