It is 10 years since the al-Qaeda leader was killed. We look at the US special forces operation that finally tracked him down to a city in northern Pakistan, the 1979 siege of the Grand Mosque in Mecca, one of the events that shaped his world view; we talk to a Western-based journalist who met him, hear from a survivor of the attacks on the US embassies in Nairobi and Dar es Salaam in 1998 and hear about the hunt for the al-Qaeda leader in the mountains of Afghanistan after 9/11.
