More on Osama.

A CIA analyst who played a lead role in locating Osama bin Laden was placed under protection by the US spy agency this month because of new threat information indicating that he might be targeted by Al Qaeda, say US officials.  

A US official said that the decision was driven by information about possible efforts by Al Qaeda to seek revenge for the May 2 US raid that ended with the death of bin Laden at his hideout in Pakistan's garrison town of Abbottabad.
