Jury selection begins Monday in the sentencing phase of the trial of the only person prosecuted in the United States for the September 11, 2001 attacks.
Five hundred potential jurors have been summoned to a U.S. court in Virginia to answer a questionnaire in the case.
It is expected to take a month to choose 12 jurors and six alternates. They will decide if Moussaoui should receive the death penalty or life in prison. Opening statements start March 6. The sentencing phase could last three months.
Last April, Moussaoui pleaded guilty to conspiring to fly a plane into the White House.
He was arrested in the state of Minnesota before the September 11, 2001 attacks, while training to fly a Boeing 747.
Nearly 3,000 people died when four hijacked airliners crashed into the World Trade Center, the Pentagon and a Pennsylvania field.Some information for this report was provided by AP.
