Osama Bin Laden exile question

Does anyone know the reason Osama was exiled from his home country of Saudi Arabia?

It should be obvious, I guess. Osama was exiled from Saudi Arabia for his support of terrorist groups. From apbnews.com:

A little background might be useful in understanding what ultimately led to his exile. Same source:

Also, bin Laden supporters were responsible for the 1993 WTC bombing, as well as the 1998 African embassy bombings, and the 2000 USS Cole attack (apparently). I’m glad I researched this, I never made the connection between bin Laden and the attacks on American Rangers in the Sudan before.

Oh and please, no “All The Base are Belong to Us” jokes. :wink:

The Chicago Tribune said he was put under “House Arrest” in Saudi Arabia. Was he actually exiled? I mean told to get out? Or did he leave to avoid being put under arrest?
