Moussaoui says he knew Twin Towers would be hit

Al-Qaida conspirator Zacarias Moussaoui testified Monday he knew the World Trade Center was going to be attacked but was not part of the plot and didn't know the details. Taking the stand in his own defense in his death-penalty trial, Moussaoui said he declined to become a suicide pilot in some future attack when asked by a senior al-Qaida official in 1999. "I had knowledge that the Twin Towers would be hit," Moussaoui said. "I didn't know the details of this."
