The convicted Sept. 11 conspirator, Zacarias Moussaoui, began serving his life sentence without the possibility of parole on Saturday, the U.S. Marshals Service said.

Moussaoui, 37, was flown Friday night to a super maximum-security federal prison in Florence, Colorado, from aAlexandria, Virginia, detention center. A team of deputy marshals delivered him to the prison early Saturday.

He will serve his jail term in a two-meter-by-3.5-meter individual cell equipped with a concrete bed, stool and desk, as well as a toilet and a shower.

Moussaoui, a Frenchman of Moroccan descent, was detained beforethe Sept. 11, 2001, attacks, and he pleaded guilty last year to six charges of terrorism connected to the attacks. He was not charged with direct involvement in the plot.

He was sentenced to life in prison last week, but appealed the sentence on Friday against the judge's refusal to allow him to change his guilty plea on the six conspiracy charges.

Moussaoui is the only person to have been charged and tried in the United States in relation to the terrorist attacks on New Yorkand Washington, which killed nearly 3,000 people.

At the supermax prison, which houses some 400 of the most dangerous criminals in the United States, Moussaoui will have to spend 23 hours a day in his cell and be allowed the remaining houroutside for physical exercise.
