US-led forces have yet to uncover any weapons of mass destruction, although the search for Iraq's banned weapons was a primary reason for the invasion.

Officials at the Central Intelligence Agency told Time that they would present US lawmakers with fresh evidence, in a bid to overcome growing doubts about the quality of the information that led to the war.

"There was a predisposition in this administration to assume the worst about Saddam," a senior military officer told the magazine.

"They were inclined to see and interpret evidence a particular way to support a very deeply held conviction," said the recently retired officer, who was deeply involved in the war planning.

"I just think they felt there needed to be some sort of rallying point for the American people. I think they said it sincerely, but I also think that at the end of the day, we'll find out their interpretations of the intelligence were wrong."

Meanwhile, the US civil administrator for Iraq, Paul Bremer, told the magazine that the United States was not receiving enough good intelligence to quickly track down Saddam.

"We are not getting actionable -- timely and accurate -- intelligence. It's a hard job," he said.

"I admit I don't think our communications with average Iraqis have been good," Bremer added.

"I think it's important that we capture or kill Saddam, because it affects the political psychology of the place," he said.
