The mastermind behind the 1993 World Trade Center bombing has died in prison at the age of 78, his son told Reuters on Saturday. Omar Abdel Rahman, the Egyptian terrorist dubbed the “blind sheik,” was serving life in prison for his role in the 1993 bombing and plans to attack other sites, including FBI headquarters in New York and the United Nations. His son, Ammar, told Reuters his family had received word of the death from a U.S. representative. No further details were disclosed. The 1993 attack left six people dead and more than 1,000 others wounded. At his sentencing over the attack, Rahman urged his followers to carry out more attacks against the “infidel” America, vowing that “nothing will remain” of the country.
