North Sentinel Island: India's Forbidden Isle & Its Uncontacted Tribe

• North Sentinel Island, part of India's Andaman and Nicobar Islands, is strictly off-limits to all outsiders.
• It is home to the Sentinelese, one of the last uncontacted tribes, who have lived in isolation for over 50,000 years.
• The Indian government declared it a protected tribal reserve in 1956, enforcing a five-kilometre exclusion zone for the tribe's protection.
• The Sentinelese fiercely defend their island, attacking outsiders, and lack immunity to common diseases, making isolation vital for their survival.
• Attempts by outsiders to approach the island have resulted in tragic deaths, including fishermen in 2006 and missionary John Allen Chau in 2018.
