The five alleged terrorists accused of plotting the September 11 attacks have appeared at a military hearing at Guantanamo Bay.
The alleged mastermind behind the attack, Kahlid Sheikh Mohammed, sang a song of praise to Allah in court, dismissed his defence team and said he welcomed the death penalty so he could die a martyr.
All five were arrested between 2002 and 2003, and transferred to the infamous base in 2006, after spending years in secret CIA prisons.
The trials have already been overshadowed by the controversy surrounding their arrests and whether the so-called confessions were exacted under torture.
Earlier in the year the CIA admitted that Sheikh Mohammed was subjected to simulated drowning known as “water-bording”, which has been denounced as torture.
Defence lawyers say they will challenge any attempt to introduce any evidence tainted by abuse.
