Defense Secretary Panetta told CBS’ "60 Minutes" on Sunday that he remains convinced that someone in the Pakistani government must have had an idea that a person of interest was in the compound where Osama bin Laden was killed. In the interview, Panetta acknowledged a Pakistani doctor, Shakil Afridi, provided information to the United States that helped identify the al-Qaida leader. After the raid, Pakistan arrested Afridi and has accused him of treason.

According to the BBC, the report, based on 27,000 interrogations with captured Taliban, al-Qaida and other fighters, states: "As this document is derived directly from insurgents it should be considered informational and not necessarily analytical."
