What Happened at Hiroshima
8.30pm, BBC One
Eighty years after the atomic bomb attack, a flame burns in the middle of Hiroshima Peace Memorial Park in Japan. It will only go out when all nuclear weapons are destroyed, but we are moving further and further away from that point. Jordan Dunbar meets survivors and campaigners who share how horrified they are about the state of the nuclear threat today. It is moving and pressing, but limited to just half an hour. Hollie Richardson
