Compound where Osama was found

US forces finally found al Qaeda leader Osama bin Laden not in the rugged mountains of Afghanistan's border, but in a million-dollar compound, with his youngest wife, U.S. officials said early on Monday.

They were led to the fortress-like three-story building after more than four years tracking one of bin Laden's most trusted couriers, whom U.S. officials said was identified by men captured after the Sept. 11, 2001 attacks.

"Detainees also identified this man as one of the few al Qaeda couriers trusted by bin Laden. They indicated he might be living with or protected by bin Laden," a senior administration official said in a briefing for reporters.

Bin Laden was finally found -- more than 9-1/2 years after the 2001 attacks on the United States -- after authorities discovered in August 2010 that the courier lived with his brother and their families in an unusual and extremely high-security building, officials said.

"When we saw the compound where the brothers lived, we were shocked by what we saw: an extraordinarily unique compound," a senior administration official said.

"The bottom line of our collection and our analysis was that we had high confidence that the compound harbored a high-value terrorist target. The experts who worked this issue for years assessed that there was a strong probability that the terrorist who was hiding there was Osama bin Laden," another administration official said.
