Washington (CNN) -- A Navy SEAL team that fought its way upstairs at Osama bin Laden's compound killed him with rapid-fire shots to his chest and forehead, according to a U.S. official who has seen military reports of the raid. The unarmed bin Laden, who the White House said put up some form of resistance, was moving when he was first shot, the official on Wednesday told CNN Pentagon correspondent Barbara Starr. Sen. Dianne Feinstein, chairwoman of the Senate Intelligence Committee, told CNN that weapons were near bin Laden, who died on an upper floor of the compound toward the end of the nearly 40-minute raid. "He was right there and going to get those arms. You really can't take a chance."
