'Guilty' 9/11 defendants face death penalty

The self-styled mastermind behind the September 11 terror attacks and four of his co-defendants face possible execution after telling a military judge at Guantanamo Bay that they wanted to plead guilty.

Khalid Sheikh Mohammed and the four others requested an “immediate hearing” to confess to their parts in the terror attacks which killed nearly 3,000 people more than seven years ago.
