NEW YORK -- A CIA report released Tuesday blames the top leadership of the agency for major lapses in fighting al-Qaida and outlines how intelligence officials missed numerous opportunities to thwart two hijackers prior to the Sept. 11 attacks.

The 19-page executive summary, written by the CIA's inspector general, finds extensive fault with the actions of former director George Tenet and other CIA leaders.

"They did not always work effectively and cooperatively," the report said.

However, the inspector general's review team found no "single point of failure nor a silver bullet" that would have stopped the Sept. 11 attacks.

While stating no CIA employee violated any law or engaged in misconduct, the report details a series of failings including:

Tenet and the agencies under his supervision lacked a comprehensive strategic plan to counter al-Qaida prior to Sept. 11.

The CIA's analysis of the terror threat before September 2001, was lacking.

Counter terror funding was ineffectively managed.

The CIA station monitoring bin Laden was overworked and lacked expertise and training.

Information about two of the hijackers including their travel to the U.S. in the summer of 2001 was not shared in a timely manner with law enforcement agencies.

While heaping blame on Tenet, the report also credits him with trying to be forcefully engaged in counterterrorism efforts.

In a statement, Tenet said the inspector general is "flat wrong" about the lack of a plan.

"There was in fact a robust plan, marked by extraordinary effort," he said. "Without such an effort, we would not have been able to give the president a plan on September 15, 2001, that led to the routing of the Taliban, chasing al-Qaida from its Afghan sanctuary and combating terrorists across 92 countries," he said.

The full report was completed in 2005 but has been kept secret because CIA officials said sources and methods could be compromised. Current CIA Director Michael Hayden said he opposed the release of the summary.

"I thought release of this report would distract officers serving their country on the front lines of a global conflict," Hayden said. "It will, at a minimum, consume time and attention revisiting ground that is already well-plowed."

Congress mandated the release of the inspector's general summary. The findings support a congressional review that also singled out the CIA for serious failures prior to Sept. 11.
