The Telegraph reports:

A senior lieutenant to Osama bin Laden has told US interrogators that the al-Qa’eda leader’s big mouth was a security liability.

Khalid Sheikh Mohammed also complained that the schemes bin Laden approved lacked destructive ambition….

..Mohammed, held in American custody at an unknown location since his capture in Pakistan three years ago, portrays himself as a brilliant terrorist manager.

Throughout the discussion, he is almost contemptuous of the wealthy bin Laden, who held the purse strings.

According to Mohammed, bin Laden lacked inspiration and vision. The Saudi failed to understand the basic security requirements of terrorist plots, such as keeping silent about impending attacks. Mohammed cites bin Laden’s decision to inform a group of visitors to his Afghan headquarters that he was about to launch a major attack on American interests.

Then he told trainee terrorists at the al-Farooq training camp “to pray for the success of a major operation involving 20 martyrs”.

Mohammed and a fellow terrorist manager, Mohammed Atef, who was later killed in an American air attack, were so concerned that they asked bin Laden to shut up.

The men “were concerned about this lack of discretion and urged bin Laden not to make additional comments about the plot”.
