In July 1989, al Qaeda double agent “Ali Mohamed travels from Fort Bragg [North Carolina] to train the al Qaeda cell that will later execute the 1993 World Trade Center bombing and the Day of Terror plot to blow up the U.N., the FBI’s New York Office, and the bridges and tunnels into Manhattan. Over four weekends, an FBI surveillance team follows Ali’s trainees Mahmud Abouhalima, Mohammed Salameh, El Sayyid Nosair, Nidal Ayad, and Clement Rodney Hampton-El from the Al Farooq Mosque [in Brooklyn, New York] to a shooting range in Calverton, Long Island. They are photographed by the FBI firing thousands of rounds from automatic weapons.” [The 15th of the month used for date sorting purposes only.]
