Autumn 1993: US Intelligence Begins Monitoring Ali Mohamed

At some point not long after Ali Mohamed is interviewed by the FBI in the autumn of 1993, the US government begins tracking his movements and monitoring his phone calls. Eventually, this surveillance will lead US investigators to the al-Qaeda cell in Nairobi, Kenya (see Late 1994). It is not clear which governmental agency does this. Meanwhile, he continues to have periodic contact with the FBI. They are especially interested in what he knows about bin Laden, as bin Laden’s importance becomes increasingly evident.
