A former FBI agent has accused the CIA of deliberately withholding photographs and information about two al-Qaeda operatives living in the United States before the Sept. 11 attacks. The agent, Ali Soufan, writes in a new book that the CIA rejected repeated FBI requests for information before 9/11 about possible al-Qaeda operatives. Then, hours after the World Trade Center was attacked, Soufan claims a CIA official in Yemen finally turned over the material that the FBI had requested months earlier. The CIA’s files included photographs of two of the hijackers who had been living in California. The CIA reportedly became aware of one of the hijackers, Nawaf al-Hazmi, a few days after he attended a secret planning meeting of al-Qaeda in Malaysia in January 2000.
