Mohamed, a former US Army sergeant, then will continue to work for al-Qaeda for a number of years. He trains bin Laden's personal bodyguards and trains a terrorist cell in Kenya that later blows up the US embassy there. Meanwhile, at least between 1993 and 1997, he tells secrets to the FBI about al-Qaeda's operations.
He is arrested in late 1998 and subsequently convicted of his role in the 1998 US embassy bombing in Kenya.
