The Maha Kumbh Mela has got underway in northern India, with organisers expecting over 400 million visitors throughout the festival. In this week's show, we speak to India's permanent representative to UNESCO, who discusses how the Hindu festival is being used as a soft-power tool by New Delhi. Plus, we bring you a report on how Afghan migrants in Pakistan fear deportation. Finally, we see how the political chaos in South Korea is driving young women and men apart.
