The last time we heard a squeak from him was on June 3 this year.
The world's most notorious terrorist outsmarted America by releasing a menacing message as Air Force One touched down on Saudi Arabian soil at the start of Barack Obama's first and much vaunted Middle East tour.
Even before the new President alighted at Riyadh airport to shake hands with Prince Abdullah, Bin Laden's words were being aired on TV, radio and the internet across every continent.

It was yet another propaganda coup for the 52-year-old Al Qaeda leader. In the audiotape delivered to the Arab news network Al Jazeera, Bin Laden said that America and her Western allies were sowing seeds of hatred in the Muslim world and deserved dire consequences.
It was the kind of rant we have heard from him before, and the response from British and U.S. intelligence services was equally predictable.
They insisted that the details on the tape, of the President's visit and other contemporary events, proved that the mastermind of 9/11, America's worst ever terrorist atrocity, was still alive - and that the hunt for him must go on.
