India is facing a "moral epidemic" in form of child abuse, he said, adding that he himself is unable to look into the eyes of victims and their families.
The Nobel Laureate shared the ordeal of the father of a young girl who was gang-raped and murdered in Shimla recently.

Asked on the tragedy of children dying in Gorakhpur due to lack of oxygen, he said, "these deaths are a massacre and just because it has been happening, it can't be allowed to go on".
"All of us (peace laureates) wrote to Suu Kyi and even the UN secretary general called on her to help these victims, and have expressed our concern and anger over the situation," Mr Satyarthi said.
