The Guardian newspaper has revealed the CIA organized a fake vaccination program in the Pakistani town where it believed Osama bin Laden was hiding in an elaborate attempt to gain access to his compound and to obtain DNA from the al-Qaeda leader’s family. A senior Pakistani doctor who was recruited by the CIA for the project is now being held in Pakistan after being arrested by the Inter-Services Intelligence for cooperating with U.S. intelligence agents. One nurse involved in the project reportedly gained access to the bin Laden compound. Before entering, she was instructed to take in a handbag that was fitted with an electronic device. It is not clear what the device was.
