DUBAI (AFP) - Executed strongman Saddam Hussein's fugitive number two Izzat Ibrahim al-Duri called on Iraqi insurgents to make a final push against US troops, in an audio message attributed to him on Tuesday. Ibrahim, the most senior member of Saddam's regime still at large, urged Iraqis to "strike the enemy everywhere... to make this year... decisive for victory," in the purported message aired by Dubai-based satellite Al-Arabiya. He called on President George W Bush to "come clean about the scale of US losses" and to "end an experiment that has now lasted more than five years." Ibrahim, who was Saddam's number two in the decision-making Revolutionary Command Council, has had a 10-million-dollar US bounty on his head since November 2003. US commanders have long accused him of being the paymaster of many of the attacks on their troops, using Saddam's hidden stashes of hard currency to buy jobless Iraqis to serve as footsoldiers in the insurgency. Thousands of US troops have taken part in the search for the fugitive leader, who was widely feared as one of the hard men of the old regime. Ordinary Iraqis nicknamed him the "iceman" because he once sold blocks of ice on the streets of the main northern city of Mosul. In September 2007, former prime minister Iyad Allawi said in an interview with Al-Arabiya that he had organised clandestine meetings between senior US officials and envoys of Ibrahim. Allawi said he himself had taken part in some of the meetings, which involved members of Saddam's banned Baath party now headed by Ibrahim. Allawi, who served as interim prime minister from June 2004 to April 2005, formed an opposition group in exile during Saddam's rule that included many dissident Baathists and army officers.
