Alleged terrorist mastermind Khalid Sheikh Mohammed called the September 11 attack a “noble victory” and branded President Barack Obama a liar in a letter released by the US military’s war crimes court.

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.

Six men have been charged with committing a total of 169 offences in the September 11 2001 terror attacks, the Pentagon said today.

Six Guantanamo Bay inmates will be charged for the September 11 attacks on America today, officials said.
