CNN: [Updated 12:27 p.m. ET] Senior defense officials said that for a majority of the 40 minute operation at the Abbottobad compound, special forces were involved in a firefight - clearing their way through two other floors before they reached Osama bin Laden.
Bin Laden was not killed until the last five to ten minutes of the firefight, officials said.
Bin Laden and his family lived on the 2nd and 3rd floors of the 3-story building, and those floors were cleared last, the official said. The official says one of bin Laden’s own wives identified his body to U.S. forces, after the team made visual identification themselves.
U.S. forces also recovered what a senior Intelligence official is calling “quite a bit of material.”
“There’s a robust collection of materials we need to sift through, and we hope to find valuable intelligence that will lead us to other players in al Qaeda," a senior intelligence official said.
The official added a Task Force has been set up “because of the sheer volume of material collected. That material is currently being exploited and analyzed.”
