Osama bin Laden urged his followers to concentrate on attacking Americans during his years in hiding - and asked potential jihadis to fill in job application forms to become al-Qaida terrorists.
US intelligence officials have released 103 documents seized in the al-Qaida leader's compound during the raid in which the mastermind of the September 11, 2001 terror attacks was killed.
The documents include a fill-in-the-blanks job application for terrorist candidates that ranges from typical questions about education and hobbies to "Do you wish to execute a suicide operation?"
It tells applicants to "please write clearly and legibly" and asks them if they have ever been convicted of a crime, before veering into more chilling territory, including: "Who should we contact in case you become a martyr?"
In one letter, bin Laden urges one of his deputies to inform "our brothers" they must keep their focus on fighting Americans. Their "job is to uproot the obnoxious tree by concentrating on its American trunk, and to avoid being occupied with the local security forces", bin Laden wrote.
Another letter mocks US President George Bush's "war on terror", saying it had not achieved stability in Iraq or Afghanistan and questioning why US troops were "searching for the lost phantom" of WMD in Iraq.
