Khalid Sheikh Mohammed, the man accused of orchestrating the September 11 attacks, along with two of his co-conspirators detained at the US military prison in Guantanamo Bay, Cuba, have consented to plead guilty, according to a Wednesday announcement by the Pentagon. The Pentagon did not provide further details on the plea agreements. An anonymous US official revealed that the plea agreements likely involved guilty pleas in return for avoiding the death penalty. The official noted that the terms of the agreement had not been made public but did not rule out a plea for a life sentence. Mohammed is the most notorious inmate at the Guantanamo Bay detention facility, established in 2002 by then-U.S. President George W. Bush to detain foreign militant suspects following the September 11, 2001 attacks. The facility once housed about 800 inmates but now holds 30. Mohammed is charged with planning the hijacking of commercial passenger aircraft to crash into the World Trade Center in New York City and the Pentagon. The 9/11 attacks resulted in nearly 3,000 deaths and led the United States into a two-decade war in Afghanistan. His interrogations have been closely watched, with a 2014 Senate Intelligence Committee report revealing that Mohammed was subjected to waterboarding at least 183 times. The Pentagon also announced plea deals for two other detainees: Walid Muhammad Salih Mubarak Bin 'Attash and Mustafa Ahmed Adam al Hawsawi. The three men were initially charged together and arraigned on June 5, 2008, and again on May 5, 2012. U.S. Senate Republican Leader Mitch McConnell criticized the plea deals, stating, "The only thing worse than negotiating with terrorists is negotiating with them after they are in custody," accusing the Biden administration of "cowardice in the face of terror."
