Caste-based discrimination blights the lives of hundreds of millions of people around the world, and the World Conference Against Racism should have the issue squarely on its agenda, Human Rights Watch urged in a new report released today. The 60-page report, Caste Discrimination: A Global Concern, focuses on the Dalits or so-called untouchables of South Asia-including Nepal, Bangladesh, India, Sri Lanka, and Pakistan-as well the Buraku people of Japan, the Osu of Nigeria, and certain groups in Senegal and Mauritania who also suffer from caste-based discrimination.
