Three U.S. officials say American forces were led to Osama bin Laden by his most trusted courier, a Kuwaiti-born man named Sheikh Abu Ahmed.
Ahmed was a shadowy figure for U.S. intelligence, someone it took many years to identify. For a long time, intelligence officials knew him only by his nom de guerre, Abu Ahmed al-Kuwaiti. The first indications about his significance came from CIA detainees shortly after the Sept. 11, 2001, terrorist attacks.
Ahmed and his brother were killed in the same predawn raid Monday that left bin Laden dead.
The officials spoke on condition of anonymity because they were not authorized to discuss the matter.
