On Wednesday, Japan observed a minute of silence to mark the 69th anniversary of the US atomic bombing of Hiroshima.
More than 45,000 people, including Japanese Prime Minister Shinzo Abe and survivors of the attack, gathered at the southern city's Peace Park to mark the anniversary of the bombing at the exact local time, 8.15 am.
On 6 August 1945, a nuclear bomb called "Little Boy" was dropped by an American B-29 bomber, the 'Enola Gay', which was flown by Colonel Paul Tibbets.
Little Boy was the first nuclear bomb, which was used in the warfare on the Japanese city of Hiroshima, according to BBC. The bomb exploded 1,900ft (580 meters) above the ground, killing more than 80,000 people instantly.
The radiation, heat and injuries took the final death toll to 135,000. Three days later, Americans dropped a second nuclear bomb called "Fat Man" on the city of Nagasaki, killing more than 40,000 people instantly.
