USA | Judge throws out KSM confession in 9/11 case in blow to prosecution

The ruling throws another wrench into the long-running death penalty case involving Khalid Sheikh Mohammed on the eve of the 25th anniversary of the deadliest U.S. terrorist strikes.

A U.S. military judge has thrown out Khalid Sheikh Mohammed's 2007 confession to FBI agents about his alleged lead role in the 9/11 attacks, ruling that it wasn’t given voluntarily and can’t be used against him at trial.

The Aug. 28 ruling by the trial judge, Air Force Lt. Col. Michael Schrama, throws yet another wrench into the long-running death penalty case on the eve of the 25th anniversary of America’s deadliest terrorist strike that killed nearly 3,000 people.

Last month, a U.S. appeals court refused to allow Mohammed and two of his co-defendants to plead guilty under earlier agreements that would have spared them the death penalty.

Military prosecutors have yet to say whether they will appeal the ruling, which would further delay a potential trial for Mohammed and three alleged co-conspirators. Earlier in the week, Schrama had set a trial date for June 2028.

The ruling strips prosecutors of what they have said is the centerpiece of their prosecution of Mohammed.

Mohammed, known informally as KSM, has on various occasions boasted about his role in orchestrating the coordinated series of suicide plane hijackings that took down the twin towers of New York’s World Trade Center and damaged the Pentagon on Sept. 11, 2001. A third hijacked plane, United Airlines Flight 93, crashed near Shanksville, Pennsylvania, after passengers and crew members fought back.

Mohammed was described as the “principal architect of the 9/11 attacks” in the 2004 report by the 9/11 Commission.

In April 2002, nearly a year before his capture, KSM invited al-Jazeera journalist Yosri Fouda to meet secretly with him and top aide Ramzi bin al-Shib in Pakistan, where they discussed the Tuesday morning attacks at length, Fouda would later report.

“Summoning every thread of experience and courage, I looked Khalid in the eye and asked: 'Did you do it?'" Fouda wrote in a 2003 story after Mohammed’s capture in Pakistan, adding that the “reference to September 11 was implicit.”

“Khalid responded with little fanfare: ‘I am the head of the al-Qaeda military committee,’ he began, ‘and Ramzi is the coordinator of the Holy Tuesday operation. And yes, we did it.’"

Mohammed made similar admissions to FBI agents over several days of interviews at the U.S. military base at Guantanamo Bay, Cuba, in 2007.

But Schrama ruled that those statements were inadmissible because of how they were obtained.

KSM, a Pakistani engineer who went to college in the United States, was subjected to waterboarding and other brutal interrogation measures in secret CIA prisons before being transferred to Guantanamo in 2006.

Schrama said military prosecutors had failed to prove that Mohammed’s 2007 statements were voluntarily given, according to The New York Times, which cited lawyers who had reviewed it.

Prosecutors had already agreed to exclude statements that KSM had made during his time in CIA custody. But they were hoping that his admissions of guilt to a “clean team” of FBI agents—including one of the original case agents, Frank Pellegrino—would be admissible.

Schrama concluded, however, that those later interrogations by the FBI were tainted by Mohammed’s earlier CIA treatment, in that he feared that he would be subjected to brutal interrogation tactics again if he refused to cooperate, the Times reported.

The 45-page ruling has not been released publicly, pending a military security review, the Times said. CBS News also reported on Schrama’s decision to throw out Mohammed’s confession.

The chief prosecutor, Rear Adm. Aaron Rugh, told The Times his team would review the decision before deciding whether to appeal.

The ruling comes days after Schrama ruled that Mohammed and three co-defendants—Walid Muhammad Salih Mubarak bin 'Atash, Mustafa Ahmed Adam al Hawsawi, and Ali Abdul Aziz Ali—will stand trial starting on June 5, 2028.

For the past 14 years, the military commission proceedings have been delayed repeatedly by disputes over the defendants' treatment in CIA custody and the admissibility of evidence gathered against them.

Prosecutors had appeared to secure a major victory in the case in July 2024 when Mohammed bin 'Atash and Hawsawi agreed to plead guilty to the charges in exchange for sparing their lives.

The agreement had been accepted by an official overseeing the Pentagon's Guantanamo war tribunal. But within days, it was revoked by President Joe Biden’s then-Defense Secretary Lloyd Austin after criticism from Republican lawmakers.

Mohammed remains the most well-known inmate at the Guantanamo detention facility, which was set up in 2002 by then-President George W. Bush to house foreign militant suspects after the 9/11 attacks.
