The al-Jazeera Arabic television station reports that alleged al-Qaeda operatives initially planned to attack nuclear installations rather than the World Trade Center. Al-Jazeera says it has interviewed two senior al-Qaeda members who made the claim - Khalid Sheikh Mohammed, allegedly one of Bin Laden�s key lieutenants, and Ramzi Binalshibh, who is said to have shared an apartment in Hamburg with Mohammed Atta, the alleged ringleader of the hijackers.
