The World Trade Center bombing was a terrorist attack that occurred on 26 February 1993, when a car bomb was detonated below Tower One of the World Trade Center in New York City, New York. The 1,500 lb (680 kg) urea nitrate-hydrogen gas enhanced device was intended to knock the North Tower (Tower 1) into the South Tower (Tower 2), to bring both towers down and kill thousands of people. It failed to do so, but killed six civilians and injured 1,042, including 919 civilians (including an EMS worker), 88 firefighters, and 35 police officers.
