On 9 August 2015, it will be 70 years since the US dropped an atomic bomb on Nagasaki, killing more than 70,000 people.

One survivor has shown his wounds from the day, to highlight the lasting effects of the atrocity.

86-year-old Sumiteru Taniguchi was just 16 years old when the bomb devastated his city.

Speaking to the Associated Press, he recalled how he was out on his job as a delivery boy when he was thrown from his bicycle by the blast.

Stunned, he wandered in a daze for three days, unable to process the event or his injuries. He was conscious that he could feel fabric-like rags hanging from his back, he later found out that it was his flesh- ripped from his body and dangling from his shoulders.

He was taken to a hospital, where he lay on his stomach for 21 months whilst the wounds on his arms and back were tended to.

Because he was still just a growing teenager, his bones grew around his wounds and exposed bones. This meant that the joints in one of his arms became locked, rendering it immobile for life.

He now heads a Nagasaki survivors group working against nuclear proliferation. However, 86-year-old's health problems are limiting the amount of involvement which he can have in the movement.

He showed his scars and told his story to Associated Press, explaining as he slipped his shirt back on: "I want this to be the end."
