Reporting live from the Japanese city’s commemoration events, Peter hears powerful testimonies from people who survived the bomb blast – which is estimated to have killed around 140,000 people.

Hear from a Japanese woman whose school was obliterated, but who survived because she was helping out at a military base on the edge of the city. Peter also talks to one of the American physicists – now in his 90s – who helped develop the atomic bombs at the Manhattan Project, and who was on the Pacific island of Tinian when the US bomber the Enola Gay set off on its mission. And Peter meets Hiroshima residents to understand what the aftermath of the bomb has been on the city, Japan, and the world, as well as people who have travelled from across the globe to take part in the commemorations.
