Rejecting Zacarias Moussaoui’s arguments, federal appeals court Monday upheld Moussaoui’s conviction and prison term.
Moussaoui, a French citizen of Moroccan descent, is the only person who has been convicted in the nation in connection to Sept. 11 attacks in 2001.
Moussaoui had pleaded guilty in 2005 saying that he was a part of the al-Qaeda conspiracy that led to attacks on the World Trade Center and the Pentagon that killed around 3000 people.
He also stated that he was supposed to hijack a fifth plane and crash it into the White House.
Moussaoui was convicted of several counts of conspiracy, which included to commit acts of terrorism and destroy aircraft. In 2006, he was sentenced to life imprisonment.
