Today marks 70 years since the atomic bomb was dropped on Hiroshima, Japan, on Aug. 6, 1945.
About 140,000 people are estimated to have been killed in the world’s first nuclear attack, including those who survived the bombing itself but died soon afterward due to severe radiation exposure.
The bomb’s destructive power was unprecedented, incinerating buildings and people. It left lifelong physical and emotional scars on survivors.
