American officials have interviewed three of Osama bin Laden's widows in Pakistan.
The women survived the raid by US Special Forces on Bin Laden's compound in Abbottabad, in which the al Qaeda leader was killed.
The White House would not discuss what was said during the interviews. The BBC reports, however, that one official said that the interviews had not been particularly forthcoming.
One of the widows has told Pakistani investigators that Bin Laden lived in Pakistan for more than seven years.
Another has said she moved to Abbottabad in 2006, a year after their home was built, and had never left its upper floors.
Pakistan has said it will repatriate the widows and their children. One of the women is from Yemen, the other two are from Saudi Arabia.
