According to U.S. officials, two U.S. helicopters swept into the compound at 1:30 and 2:00 a.m. Sunday morning. Twenty to 25 U.S. Navy Seals under the command of the Joint Special Operations Command in cooperation with the CIA stormed the compound and engaged Bin Laden and his men in a firefight, killed Bin Laden and all those with him.
Two Bin Laden couriers were killed, as was one of Osama Bin Laden's son, as was a woman reportedly used as a shield by one of the men. Other women and children were present in the compound, according to Pakistani officials, but were not harmed. U.S. officials said that Bin Laden himself did fire his weapon during the fight.
Some time after Sept. 11, detainees held by the U.S. told interrogators about a man believed to work as a courier for bin Laden, senior administration officials said. The man was described by detainees as a protégé of Khalid Sheikh Mohammed, and “one of the few Al Qaeda couriers trusted by bin laden.”
Initially, intelligence officials only had the man’s nickname, but they discovered his real name four years ago.
Two years ago, intelligence officials began to identify areas of Pakistan where the courier and his brother operated, and the great security precautions the two men took aroused U.S. suspicions.
Last August, intelligence officials tracked the men to their residence in Abbottabad, Pakistan, a relatively wealthy town 35 miles north of Islamabad where many retired military officers live.
The compound was eight times larger than any other home in the area.It was surrounded by walls measuring 12 feet to 18 feet that were topped with barbed wire. There were additional inner walls that sectioned off parts of the compound and entry was restricted by two security gates. And the residents burned their trash instead of leaving it outside for pickup. There was a three-story house on the site, with a 7-foot privacy wall on the top floor.
While the two brothers, the couriers, had no known source of income,the compound was built in 2005 and valued at $1 million. That led intelligence officials to conclude that it must have been built to hold a high-value member of Al Qaeda.
A helicopter involved in the raid suffered mechanical failure and was blown up by the American team, none of whom were killed or injured. The Pakistani government was not informed of the raid until after it was over.
