Washington (CNN) -- Osama bin Laden was not armed when he was shot and killed by U.S. forces in the assault on his compound in Pakistan, White House Press Secretary Jay Carney said Tuesday.
The al Qaeda leader resisted the assault on his compound, Carney said, adding: "I think resistance does not require a firearm."
Carney described how the U.S. Navy SEALs carrying out the operation went floor-to-floor clearing the three-story compound where bin Laden's family lived with another family.
Three people were killed on the first floor, including a woman, and then the U.S. forces moved upstairs where they found bin Laden, Carney said.
"Bin Laden was then shot and killed," Carney said. "He was not armed."
On Monday, President Barack Obama's top counterterrorism adviser, John Brennan, said bin Laden was resisting and had a weapon, though it was unclear if bin Laden had fired a shot.
