Saddam Hussein's regime was not directly in cooperation with al Qaeda before the U.S. invasion of Iraq, according to a declassified Defense Department report.

Captured Iraqi documents and intelligence interrogations of Saddam Hussein and two former aides "all confirmed" that, the report said.

The declassified version of the report, by acting Inspector General Thomas F. Gimble, also contains new details about the intelligence community's prewar consensus.

It shows that the Iraqi government and al Qaeda figures had only limited contacts, and about its judgments that reports of deeper links were based on dubious or unconfirmed information, The Washington Post reported on Friday.

The Pentagon report had been released in summary form in February, the newspaper said.

The Pentagon report's release came on the same day that Vice President Dick Cheney, appearing on a radio program, repeated his allegation that al Qaeda was operating inside Iraq "before we ever launched" the war, under the direction of Abu Musab al-Zarqawi, the terrorist killed last June.

"This is al Qaeda operating in Iraq," Cheney said about Zarqawi, who he said had "led the charge for Iraq." Cheney cited the alleged history to illustrate his argument that withdrawing U.S. forces from Iraq would "play right into the hands of al Qaeda."

Senate Armed Services Committee Chairman Carl M. Levin (D-Mich.), who requested the report's declassification, said in a written statement that the complete text demonstrates more fully why the inspector general concluded that a key Pentagon office -- run by then-Undersecretary of Defense Douglas J. Feith -- had inappropriately written intelligence assessments before the March 2003 invasion, alleging connections between al Qaeda and Iraq that the U.S. intelligence consensus disputed.

The report, in a passage previously marked secret, said Feith's office had asserted in a briefing given to Cheney's chief of staff in September 2002 that the relationship between Iraq and al Qaeda was "mature" and "symbiotic," marked by shared interests and evidenced by cooperation across 10 categories, including training, financing and logistics.

Instead, the Pentagon report said, the CIA had concluded in June 2002 that there were few substantiated contacts between al Qaeda operatives and Iraqi officials and had said that it lacked evidence of a long-term relationship like the ones Iraq had forged with other terrorist groups.

The CIA had separately concluded that reports of Iraqi training on weapons of mass destruction were "episodic, sketchy, or not corroborated in other channels," the inspector general's report said. It quoted an August 2002 CIA report describing the relationship as more closely resembling "two organizations trying to feel out or exploit each other" rather than cooperating operationally.

The CIA was not alone, the defense report emphasized. The Defense Intelligence Agency had concluded that year, that "available reporting is not firm enough to demonstrate an ongoing relationship" between the Iraqi regime and al Qaeda, it said.

But the contrary conclusions reached by Feith's office -- and leaked to the conservative Weekly Standard magazine before the war-- were publicly praised by Cheney as the best source of information on the topic, a circumstance the Pentagon report cites in documenting the impact of what it described as "inappropriate" work.
