OSAKA/HIROSHIMA -- This week marks the 75th anniversary of the atomic bombings of Hiroshima and Nagasaki -- the world's first nuclear attacks that obliterated hundreds of thousands of people. As the number of survivors dwindles, the two cities remain steadfast in their efforts to keep the story of the horrific destruction alive.
The U.S. dropped an atomic bomb on Hiroshima on Aug. 6, 1945 and followed three days later with an attack on Nagasaki. At the time, Hiroshima had a population of 350,000 and Nagasaki 240,000. By the end of that year, an estimated 140,000 people had perished in Hiroshima and 70,000 in Nagasaki.
