On this week's show: Young Norwegians return to Utoya four years after a horrific massacre, and why a Crimean broadcaster has set up shop in Kyiv. We also hear from a survivor of the atomic bomb that devastated Hiroshima, a victim of Stalin's mass deportations, and speak to a Serb and a Croat about growing up in the wake of conflict. Plus, a birthday nod to reggae legend Bob Marley.
