From 1986, MAK began to set up a network of recruiting offices in the US, the hub of which was the Al Kifah Refugee Center at the Farouq Mosque on Brooklyn's Atlantic Avenue. Among notable figures at the Brooklyn center were "double agent" Ali Mohamed, whom FBI special agent Jack Cloonan called "bin Laden's first trainer", and "Blind Sheikh" Omar Abdel-Rahman, a leading recruiter of "mujahideen" for Afghanistan. Azzam and bin Laden began to establish camps in Afghanistan in 1987.
