"White House was my 9/11 target"

ALEXANDRIA, Virginia (CNN) -- Al Qaeda conspirator Zacarias Moussaoui told a stunned courtroom Monday that he and would-be shoe bomber Richard Reid were supposed to hijack a fifth plane on September 11, 2001, and crash it into the White House. In a day of bombshell revelations, Moussaoui also admitted that he knew about al Qaeda's plot to hijack planes and fly them into the twin towers of the World Trade Center. "I had knowledge that the two towers would be hit, but I did not have the details," Moussaoui told jurors after taking the witness stand in his own defense. Moussaoui said that while he didn't know the "precise date to the day" of the planned terrorist attacks, he knew they would come after his arrest in August 2001 in Minnesota. He said he made sure he had a radio in his jail cell. When the first news reports on September 11 described a fire at the trade center, Moussaoui said, "I immediately understood."
