At 08:15 on August 6, 1945, as a nuclear bomb was falling like a stone through the skies over Hiroshima, Lee Jung-soon was on her way to elementary school.
The now-88-year-old waves her hands as if trying to push the memory away.
"My father was about to leave for work, but he suddenly came running back and told us to evacuate immediately," she recalls. "They say the streets were filled with the dead – but I was so shocked all I remember is crying. I just cried and cried."
Victims' bodies "melted away so only their eyes were visible", Ms Lee says, as a blast equivalent to 15,000 tons of TNT enveloped a city of 420,000 people. What remained in the aftermath were corpses too mangled to be identified.
"The atomic bomb… it's such a terrifying weapon."
