Washington ? A terror suspect detained at Guantanamo Bay, Cuba, was a commander for Osama bin Laden during the Soviet occupation of Afghanistan in the 1980s and helped the al-Qaida leader escape his mountain hideout at Tora Bora in 2001, according to a U.S. government document.

The document, provided to The Associated Press in response to a Freedom of Information request, says the unidentified detainee “assisted in the escape of Osama bin Laden from Tora Bora.” It is the first definitive statement from the Pentagon that bin Laden was at Tora Bora and evaded U.S. pursuers.

The detainee is not identified by name or nationality. He is described as being “associated with” al-Qaida and having called for a jihad, or holy war, against the United States.

In an indication that he might be a higher-level operative, the document says he “had bodyguards” and collaborated with regional al-Qaida leadership. “The detainee was one of Osama bin Laden’s commanders during the Soviet jihad,” it says, referring to the war against Soviet occupiers.

The events at Tora Bora were a point of contention during last year’s presidential race, and Bush as well as Vice President Dick Cheney asserted that commanders did not know whether bin Laden was there when U.S. and allied Afghan forces attacked the area in December 2001.

Cheney said last Oct. 26 that Gen. Tommy Franks, the commander of U.S. forces in Afghanistan, had “stated repeatedly it was not at all certain that bin Laden was in Tora Bora. He might have been there or in Pakistan or even Kashmir,” the Indian-controlled Himalayan region.

Franks, now retired, wrote in an opinion column in The New York Times last Oct. 19, “We don’t know to this day whether Mr. bin Laden was at Tora Bora in December 2001.” He added that assessments of his location varied, but bin Laden was “never within our grasp.”

On several occasions in the days following publication of that column, Bush cited it on the campaign trail as evidence that bin Laden could have been in any of several countries in December 2001. “That’s what Tommy Franks, who knew what he’s talking about, said,” Bush said on Oct. 27.

Sen. John Kerry, the Democratic presidential nominee, lambasted Bush during the campaign for having missed a chance to capture or kill bin Laden at Tora Bora.
