WASHINGTON, D.C. -- To millions of Americans, he's the face of evil; the only man convicted for the Sept. 11, 2001 attacks.

For five years, we've seen a still picture of Zacarias Moussaoui, but WNBC.com's Jonathan Dienst has obtained the only known video of the man found to be responsible for the thousands of deaths.

The video was shot as Moussaoui was being transferred to Supermax by U.S. Marshals, a maximum-security prison in Colorado, where he will serve out his sentence of six life terms without the chance of parole.

In the tape, Moussaoui calls out "allah akbar," which translates to "God is great."

At his sentencing, when U.S. Judge Leonie Brinkema sent Moussaoui to prison for life to "die with a whimper," the convicted terrorist declared: "God save Osama bin Laden -- you will never get him."

A jury rejected the government's case to have Moussaoui executed, deciding instead to send him to prison for life without a chance of parole.

Not all jurors were convinced that Moussaoui, who was in jail on immigration charges Sept. 11, 2001, had a significant part in the attacks, despite his boastful claims that he did.
