Dozens of people have been killed in a series of bombings across Iraq. In the latest attack this morning, at least 24 people died in a string of bomb attacks in the northern city of Kirkuk. One device targeted a police patrol while another was directed at a crowd that gathered at the scene.Elsewhere a dozen people were killed and more than 40 others injured following blasts in Baghdad’s sprawling Shi’ite district, Sadr City. Meanwhile, after meeting his national security team, the US President George Bush said al-Qaeda’s new chief in Iraq would be targeted. “I think the successor to Zarqawi is going to be on our list to bring to justice,” he said. The President’s cabinet and military advisers will continue talks at Camp David today to work out how to deploy resources in Iraq. But with his popularity ratings at a historic low, Bush cannot afford to ignore the issue of the withdrawal of US troops.
