at the possibility that Jordanian terrorist Abu Musab al-Zarqawi constituted a link between Saddam and al-Qaeda, as Colin Powell had claimed in his speech to the United Nations Security Council. The assessment concluded that there was no evidence that Saddam Hussein's regime harbored Jordanian terrorist Abu Musab al-Zarqawi. A U.S. official familiar with the new CIA assessment said intelligence analysts were unable to determine conclusively the nature of the relationship between al-Zarqawi and Saddam. "It's still being worked," he said. "It (the assessment) ... doesn't make clear-cut, bottom-line judgments" about whether Saddam's regime was aiding al-Zarqawi. The official told Knight Ridder "What is indisputable is that Zarqawi was operating out of Baghdad and was involved in a lot of bad activities," but that the report didn't conclude that Saddam's regime had provided "aid, comfort and succor" to al-Zarqawi. According to Knight Ridder, "Some officials believe that Saddam's secular regime kept an eye on al-Zarqawi, but didn't actively assist him." Knight Ridder reporters called the CIA study "the latest assessment that calls into question one of President Bush's key justifications for last year's U.S.-led invasion of Iraq." 2005 update of CIA report In October 2005, the CIA updated the 2004 report to conclude that Saddam's regime "did not have a relationship, harbor, or even turn a blind eye toward Mr. Zarqawi and his associates," according to the Senate Select Committee on Intelligence (see 2006 report below). Two counterterrorism analysts told Newsweek that Zarqawi did likely receive medical treatment in Baghdad in 2002, but that Saddam's government may never have known Zarqawi was in Iraq because Zarqawi used "false cover." An intelligence official also told Newsweek the current draft of the report says that "most evidence suggests Saddam Hussein did not provide Zarqawi safe haven before the war. It also recognizes that there are still unanswered questions and gaps in knowledge about the relationship." According to Newsweek, "The most recent CIA analysis is an update—based on fresh reporting from Iraq and interviews with former Saddam officials—of a classified report that analysts in the CIA's Directorate of Intelligence first produced more than a year ago." 2006 Pentagon study In February 2006, the Pentagon published a study of the so-called Harmony database documents captured in Afghanistan. While the study did not look specifically at allegations of Iraq's ties to al-Qaeda, it did analyze papers that offer insight into the history of the movement and
