Military prosecutors have decided to seek the death penalty for six prisoners being held at Guantanamo for allegedly playing central roles in the September 11 attacks. One of the prisoners who will be put on trial before a military commission is Khalid Sheikh Mohammed. Attorneys predict the treatment of the detainees in US custody will likely be raised before the military commission. The CIA has admitted to waterboarding Khalid Sheikh Mohammed in a secret prison. Pentagon investigators concluded in 2005 that another one of the men, Mohammed al-Qahtani, had been subjected to abusive treatment at Guantánamo, including sleep deprivation, being forced to wear a bra and being led around on a leash.
