Mysterious island is home to 60,000-year-old tribe but outsiders cannot visit because they kill

The Indian Ocean island, which is almost the size of Manhattan, has been inhabited by the indigenous Sentinelese for 60,000 years.

The tribe have severally rejected the modern world and are very violent to outsiders, even killing two men in 2006 after they were fishing nearby their North Sentinel Island.

The tribe even go as far as throwing rocks and shooting arrows at planes or helicopters, and such is the hostility they display towards outsiders that only low-quality pictures exist of the inhabitants.

Indian authorities have even gone as far as making it a crime to try to make contact with the Sentinelese.

But while it is illegal to go within three miles of the island, that has not stopped some from venturing nearby.

Survival International - which advocates for the rights of tribal groups has alleged that local fisherman are regularly entering the area - with one even stepping onto the island before he and six others were arrested by the authorities.

Survival international now fears that the survival of the tribe is under threat.

Survival International’s director, Stephen Corry, said: "The Great Andamanese tribes of India’s Andaman Islands were decimated by disease when the British colonised the islands in the 1800s.

"The most recent to be pushed into extinction was the Bo tribe, whose last member died only four years ago.

"The only way the Andamanese authorities can prevent the annihilation of another tribe is to ensure North Sentinel Island is protected from outsiders."
