North Sentinel Island: India's forbidden land where contact might mean death

North Sentinel Island is home to the Sentinelese, one of the last uncontacted tribes in the world, who have lived in complete isolation for thousands of years and resist all outside contact.

In 2018, American missionary John Allen Chau was killed after attempting to reach the island, underscoring the dangers of intrusion.

Today, the island remains strictly off-limits, not just because it is hostile, but because any contact could put an entire civilisation at risk.
