The details of bin Laden's life as a fugitive — which were first published by the Pakistani newspaper Dawn — raise fresh questions over how bin Laden was able to remain undetected for so long in Pakistan after the Sept. 11, 2001 attacks, despite being the subject of a massive international manhunt.

Yet a senior U.S. official, who is familiar with the contents recovered in bin Laden's Abbottabad house, said there was no evidence that Pakistani officials were aware of bin Laden's presence. "There was no smoking gun. We didn't find anything," he said on condition of anonymity because he was not authorized to speak about the contents of the Abbottabad house

According to the interrogation report, bin Laden lived in five safe houses and fathered four children — the two youngest born in a public hospital in Abbotabad. But investigators have only located the houses in Abbottabad and Haripur.
