Architect of 9/11 attacks Khalid Shaikh Mohammed strikes plea deal to avoid death penalty after terror mastermind spent decades at Guantanamo Bay

Three men accused of plotting the September 11 attacks, including the alleged architect, have agreed to plea deals after decades in US detention.

Khalid Sheikh Mohammed, Walid Bin Attash and Mustafa al-Hawasawi have all agreed to plead guilty to conspiracy charges in exchange for a life sentence. 

The New York Times reported on Wednesday evening that the pleas, which will see the men dodge a death penalty trial, have been approved by Pentagon officials.

All three men have been in custody in Guantanamo Bay since 2003. Mohammed is an al Qaeda militant accused of being the principal architect of the Sept. 11 attacks.

In a letter to family members of September 11 victims, chief prosecutor Rear Admiral Aaron Rugh said: ‘In exchange for the removal of the death penalty as a possible punishment, these three accused have agreed to plead guilty to all of the charged offenses, including the murder of the 2,976 people listed in the charge sheet.

The letter, seen by the Times, said the men could submit their pleas in open court as early as next week, according to the Times.

The Defense Department released a statement on Wednesday saying prosecutors had reached plea agreements with the men, without disclosing the terms.

The prosecution of the men has been troubled by repeated delays and legal disputes, especially over the legal ramifications of the interrogation under torture that the men initially underwent while in CIA custody. 

The Pentagon and the FBI advised families of the victims last August that the death penalty may have to be taken off the table in the prosecution of the men. 

They were captured at various times and places in 2002 and 2003 and sent to Guantanamo for trial in 2006.

On September 11, 2001, conspirators from al-Qaida seized control of airplanes and hit New York’s World Trade Center and the Pentagon near Washington.

A fourth plane was headed for Washington but crashed in Pennsylvania after crew members and passengers tried to storm the cockpit.

It was Mohammed who presented the very idea of such an attack on the United States to al-Qaida leader Osama bin Laden.

Mohammed also who received authorization from bin Laden to craft what became the 9/11 attacks, the United States’ 9/11 Commission concluded.

The other defendants are alleged to have supported the hijackers in various other ways.

Mohammed was captured alongside Hawsawi in March 2003 before being held in CIA prisons until their transfer to Guantanamo in 2006. 

Officially, the casualty count associated with the attacks is numbered at 2,996 – including 2,977 victims and 19 hijackers. 

Thousands more were injured, and New York bore the brunt of the death toll – with an estimated 1,600 victims in the North Tower and another thousand in the South.
