TOKYO -- The atomic bombings of Hiroshima on August 6, 1945, and Nagasaki three days later brought a scale of destruction the world had never seen. Many who survived the blasts died in the weeks, months and years that followed. Japan surrendered six days after the Nagasaki bombing, bringing an end to World War II.

HIROSHIMA, Japan -- Hiroshima on Wednesday marked the 80th anniversary of the U.S. atomic bombing of the western Japanese city, with many aging survivors expressing frustration about the growing support of global leaders for nuclear weapons as a deterrence.
