The US has formally sent to trial five suspected al-Qaeda militants believed to have planned the 9/11 terror attacks.
The five Guantanamo Bay inmates, including alleged mastermind Khalid Sheikh Mohammed, will be tried by a military commission.
They will face charges including terrorism, hijacking, conspiracy, murder and destruction of property.
They could face the death penalty if found guilty, the Pentagon confirmed.
Khalid Sheikh Mohammed and the four others - Waleed bin Attash, Ramzi Binalshibh, Ali Abd al-Aziz Ali and Mustafa Ahmad al-Hawsawi - are expected to be tried together, the Pentagon added.
They are accused of planning and executing the terror attacks of 11 September 2001, which saw hijacked planes strike New York, Washington and Shanksville, Pennsylvania.
A total of 2,976 people died in the attacks.
