The weapon used during Ramzi Yousef's 1993 attack on the World Trade Center was a truck bomb, which refers to a type of explosive device that is carried within or attached to a vehicle. In this particular incident, a rental van was filled with explosives and detonated in the underground parking garage of the World Trade Center, resulting in significant damage and loss of life.
