On February 18, 2003, an arsonist set fire to a Daegu Metro subway train as it arrived at Jungangno station in central Daegu, South Korea. The resulting blaze, which spread when a second train stopped at the same station, killed 192 people and injured another 151. It remains the deadliest loss of life in a single deliberate incident in South Korean peacetime history, surpassing the 1982 shooting rampage committed by Woo Bum-kon.
