CNN's Chris Lawrence, citing U.S. Officials, reports that the compound where bin Laden was found - in Abbotabad, Pakistan, about 100 kilometers outside Pakistan's capital of Islamabad - was three stories tall, and about eight times larger than any of the buildings around it.
An official said a "small U.S. Team" was involved in the operation at the compound - the official would not confirm any U.S. Military involvement.
An official said bin Laden resisted the assault - and was killed in the firefight
Three other men were killed in the firefight, and a woman being used as a human shield was also killed, the officials said.
There were no U.S. Casualties, the officials said. The U.S. Team was at the compound for about 40 minutes, officials said.
A U.S. Helicopter crashed during the raid because of mechanical reasons, an official said. It was destroyed, the officials said.
