A plan to hijack commercial planes and fly them into U.S. targets was reportedly incorporated into a terror strategy by Ramzi Zhmed Yousef, who was sentenced to life imprisonment for masterminding the bombing of the World Trade Center in 1993, Inquirer News Service reported. The plan was first uncovered in Manila in 1995 after police arrested four suspects in a plot to assassinate Pope John Paul II, and was passed on to U.S. officials by the Philippine government. At least four of Yousef's partners in the 1993 bombing have remained at large, increasing suspicions that they could be involved in the Sept. 12 terrorist attacks in New York and Washington, D.C.
