South Korea's younger generation is leading an empathic shift on North Korean human rights, paving the way for more action by a traditionally indifferent general public.

This is the view of a university student collective that recently held an influential exhibition focusing on North Korea's hellish prison camps. More than 25,000 people visited the exhibition in Seoul's hip art district Insadong over two weeks in February, many of them South Koreans discovering the full horror of their northern neighbours' lives for the first time.
