Osama bin Laden was caught because of a 60-second phone call. His most trusted courier, Sheikh Abu Ahmed broke the golden rule - never talk to another al-Qaeda operative on a mobile. He and other senior figures were ordered to only speak to each other face to face. Little did he know that the associate he called was being bugged by the CIA.
Kuwaiti-born Ahmed had been with bin Laden since 2001 when he vanished from the Tora Bora mountains in Afghanistan. He helped plan the 9/11 terror attacks and because he was an IT specialist, gave the hijackers instructions on how to use computers. He also delivered the tape recordings made by his leader to TV stations. Since July last year, the compound has been watched by drones, satellites and agents. CIA suspected a “high-value target” was living there but didn’t have any proof until a photo was taken of bin Laden inside the compound last month. Ahmed and his brother are now dead, both killed in the raid.
