If any group of people qualifies for the term “lost tribe” it is the Sentinelese. Like other Andaman island natives, they have managed to live for thousands of years near one of the most ancient sea routes while avoiding any influence from outside civilizations. Situated in the bay of Bengal, the Andaman islands have been known to outsiders since ancient times. Andaman islanders respond with intense hostility at any attempt of outside contact, hurling arrows and stones at any unlucky visitor approaching their shores.
The population of North Sentinel island is estimated at 250 individuals. After the Indian Ocean tsunami of 2004, there was a fear that the Sentinelese may have been wiped out, however they appear to have survived the event relatively unscathed.
In 2006, Sentinelese archers killed two fishermen who were fishing illegally within range of the island, and drove off the helicopter that was sent to retrieve their bodies with a hail of arrows. The current policy of the Indian government is to leave the islanders alone. There are currently no planned attempts to contact the Sentinelese and access to North Sentinel island is strictly forbidden.
