Special forces stormed Osama Bin Laden’s fortress only days after the Wikileaks website published new secret documents.

These made reference to named ‘couriers’ carrying Bin Laden’s message to his followers, and also to Abbottabad as a possible Al Qaeda bolthole.

America has already revealed that it was led to Bin Laden by tracking a man identified as his key courier.

When that man was found in Abbottabad, the Americans began surveillance that led to the raid.

It is now being suggested the operation had to be launched before Bin Laden knew the game was up.

The theory is based on a leaked U.S. Defence Department assessment of Guantanamo Bay prisoner Abu Faraj al-Libi, 40.

The assessment, currently available on the internet, was among information first released to newspapers including the Telegraph and the Guardian, and identifies al-Libi as an operational chief of Al Qaeda, and long-term close associate of Bin Laden.

After working at the centre of the terror network in Afghanistan for more than a decade, al-Libi fled to Pakistan following the Allied conquest of Kabul in November 2001.

The top secret document claims: ‘In July 2003 In July 2003, al-Libi received a letter from Osama Bin Laden’s designated courier, Maulawi Abd al-Khaliq Jan, requesting detainee take on the responsibility of collecting donations, organizing travel, and distributing funds to families in Pakistan.

Although the document did not suggest Bin Laden was in Abbottabad, it clearly identifies the city as known to the Americans as a possible Al Qaeda leadership bolthole, and identifies several couriers by name.
