WASHINGTON (AP) - Osama bin Laden, the mastermind behind the Sept. 11 attacks against the United States, is dead, and the U.S. is in possession of his body, a person familiar with the situation said late Sunday.
President Barack Obama was expected to address the nation on the developments Sunday night.
A senior U.S. counterterrorism official said bin Laden was killed in a ground operation in Pakistan, not by a Predator drone.
The official said it happened last week. Officials have long believed bin Laden, the most wanted man in the world, was hiding a mountainous region along the Pakistan-Afghanistan border.
The officials spoke on the condition of anonymity in order to speak ahead of the president.
