Moussaoui pleads guilty over 9/11

Zacarias Moussaoui pleaded guilty today to helping al-Qaida carry out the September 11 hijackings and said he understood he could be put to death for his role in the deadliest terror attack in US history.

US District Judge Leonie Brinkema accepted the plea at the court in Alexandria, Virginia, making the French citizen, who once lived in London the lone person to be convicted in a US court of the 2001 attacks that killed nearly 3,000 people.
