Omar Abdel-Rahman
The attack was planned by a group of conspirators including Ramzi Yousef, Sheik Omar Abdel-Rahman, El Sayyid Nosair, Mahmud Abouhalima, Mohammad Salameh, Nidal Ayyad, Ahmad Ajaj, and Abdul Rahman Yasin. They received financing from al-Qaeda member Khalid Shaikh Mohammed, Yousef's uncle, who would later allegedly admit to planning the September 11 attacks.
