US court rejects plea deal for '9/11 mastermind' Khalil Sheikh Mohammed

US court rejects plea deal for '9/11 mastermind' Khalid Sheikh Mohammed after judges in Washington DC reject agreement for life sentence without parole. Accused of orchestrating the 2001 attacks on the US, where almost 3,000 people died, Mohammed has been held in Guantanamo Bay since his capture in 2003. The plea deal, allowing families of 9/11 victims to question Mohammed, faced controversy as some sought a trial for justice, while others saw it as a chance for closure.
