WASHINGTON, Feb. 8 — A Pentagon investigation into the handling of prewar intelligence has criticized civilian Pentagon officials for conducting their own intelligence analysis to find links between Saddam Hussein and Al Qaeda, but said the officials did not violate any laws or mislead Congress, according to Congressional officials who have read the report.

The long-awaited report by the Pentagon’s acting inspector general, Thomas F. Gimble, was sent to Congress on Thursday. It is the first major review to rebuke senior officials working for Defense Secretary Donald H. Rumsfeld for the way intelligence was used before the invasion of Iraq early in 2003.

Working under Douglas J. Feith, who at the time was under secretary of defense for policy, the group “developed, produced and then disseminated alternative intelligence assessments on the Iraq and Al Qaeda relationship, which included some conclusions that were inconsistent with the consensus of the Intelligence Community, to senior decision-makers,” the report concluded. Excerpts were quoted by Senator Carl Levin, a Michigan Democrat who has long been critical of Mr. Feith and other Pentagon officials.

The report, and the dueling over its conclusions, shows that bitter divisions over the handling of prewar intelligence remain even after many of the substantive questions have been laid to rest and the principal actors have left the government.
