How is al-Qaeda connected to the 1993 World Trade Center bombing?
There are strong links. Sheikh Omar Abdel Rahman, the militant cleric convicted in the 1993 plot, once led an Egyptian group now affiliated with al-Qaeda; two of his sons are senior al-Qaeda officials. And Ramzi Ahmed Yousef, who was convicted of masterminding the 1993 attack, planned al-Qaeda’s foiled attack on American airliners over the Pacific Ocean. He is also the nephew of the former senior al-Qaeda terrorist Khalid Sheikh Mohammed, who is now in U.S. custody.
