Sources – Al-Qaida Head Bin Laden Dead

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.
