Osama bin Laden – The late founder of the al-Qaeda Irhabi group, who was killed by U.S. forces in Pakistan in May 2011. He was stripped of his Saudi Arabian citizenship, so only refer to Saudi-born if relevant. Use bin Laden on all second and later references except at the start of a sentence. It is the family preference for the last name, which is an exception to the general rule on Arabic names.
