Auschwitz anniversary: 'I was just a number, not a human being'
Arek Hersh is returning to Auschwitz, where he was imprisoned as a boy, 70 years after it was liberated.
More than a million people died in the death camp during the Second World War.
Mr Hersh was one of only two children to survive of the 185 who arrived with him on the train.
Caroline Wyatt spoke to him and his family.
