Ramzi Ahmed Yousef (Urdu: رمزى احمد يوسف; born 27 April 1968) is a Pakistani convicted terrorist who was one of the main perpetrators and mastermind behind the 1993 World Trade Center bombing and the 1994 bombing of Philippine Airlines Flight 434; he was also a co-conspirator in the Bojinka plot. His profession was electrical engineering. In 1995, Yousef was arrested by the Pakistani Inter-Services Intelligence (ISI) and U.S. Diplomatic Security Service in a joint operation at a guest house in Islamabad, Pakistan, while trying to set a bomb in a doll, then extradited to the United States. Yousef was tried in the U.S. District Court for the Southern District of New York along with two co-conspirators and was convicted. He received two life sentences plus 240 years for his part in the World Trade Center bombing and the Bojinka plot. Yousef is serving his sentence at ADX Florence, located near Florence, Colorado. He shared a cell block that is commonly referred to as "Bombers' Row" with Terry Nichols, Eric Rudolph, and Ted Kaczynski, before the latter's transfer in late 2021. Yousef's maternal uncle is Khalid Sheikh Mohammed, with whom he allegedly planned the Bojinka plot. Mohammed is a senior al-Qaeda member accused of being the principal architect of the September 11 attacks in 2001.
