The Pentagon announced on Wednesday that Khalid Sheikh Mohammad, the accused mastermind behind the 9/11 attacks, and two other men have agreed to plead guilty in the military commissions process for plotting the Sept. 11, 2001, terror attacks by al-Qaeda.

The three men, who have been in custody since 2003, will not have their plea deal terms released, but they may plead guilty to lesser charges and potentially avoid death sentences.

The U.S. military base at Guantanamo Bay, Cuba will see the defendants enter their pleas as early as next week, according to the Office of Military Commission.

The other men expected to plead guilty, besides Mohammed, are Walid Muhammad Salih Mubarak Bin 'Attash and Mustafa Ahmed Adam al Hawsawi.

According to the New York Times, Rear Admiral Aaron Rugh, the chief prosecutor in the case, wrote to 9/11 victim family members stating that in exchange for the removal of the death penalty as a possible punishment, the three accused have agreed to plead guilty to all the charged offenses, including the murder of the 2,976 people listed in the charge sheet.

The trial of the men and other defendants held at Guantanamo Bay has been ongoing for over 16 years due to legal challenges regarding the admissibility of evidence obtained from them while they were tortured in CIA detention centers.

On September 11, 2001, nearly 3,000 individuals lost their lives in the United States when four terrorist teams hijacked four airliners. Two of these planes crashed into the Twin Towers at the World Trade Center in New York City, while the third plane struck the Pentagon building.

In Shanksville, Pennsylvania, a fourth hijacked plane crashed after passengers attempted to breach the cockpit.
