It has been 70 years since the US dropped atomic bombs in the Japanese cities Hiroshima and Nagasaki in the final stage of World War II.
Boeing B-29 Superfortress Enola Gay dropped the uranium gun-type atomic bomb 'Little Boy' on Hiroshima on 6 August 1945, destroying everything in five square miles.
The second atomic weapon, a plutonium implosion-type bomb 'Fat Man' was dropped in Nagasaki three days later on 9 August by American B-29 bomber Bockscar. It exploded 1,650 feet above the city around 11.02 am local time, killing more than 40, 000 people instantly.
The two atomic bombings killed more than 2,46,000 people. Later, many others also died due to burns, radiation and other illnesses in the following months.
However, by 15 August, Japan announced its surrender to the Allies and ended the World War by signing the instrument of surrender on 2 September.
