The US has reached a plea deal with alleged 9/11 mastermind Khalid Sheikh Mohammed and two other defendants accused of plotting the 2001 terror attacks. Under the deal, Mohammed and the others agreed to plead guilty to all charges related to the 9/11 attacks that killed nearly 3,000 people. They will have a sentencing hearing but will avoid execution. The long-delayed trial of Mohammed and others was set to begin in 2021 but faced delays. This deal avoids a complicated death penalty trial process. Some experts argue this deal is the best path to finality and justice after over 20 years, but families still want the full truth about Saudi involvement.
