You might be the one who traveled over every corner of India, from superlative beaches to sky-touching mountains, but then it is free from doubt that you will be left open-mouthed to know that there are a plenty of unexplored places in India - some due to natural phenomenon and others because of the indigenous tribes that reside there.

Up to now, you might have come across recent reports about the killing of 26-year-old American missionary John Allen Chau on November 16 by tribesmen from the North Sentinel Island to keep him off from their island home.

To begin with, let us acquaint you to the 'North Sentinel Island':

It is one of the Andaman Islands, which is home to the Sentinelese community that violently discard any contact with the modern world.

The community is protected under the Andaman and Nicobar Islands Protection of Aboriginal Tribes Act of 1956 which prohibits anyone to enter the island and any approach closer than five nautical miles. The area is patrolled by the Indian navy.

Any approach by human or vessels would turn Sentinelese violent.

Earlier in 2004, the Indian government aircraft was attacked with arrows, spears, and stones while it was observing the Islanders the damage caused after the Indian Ocean Earthquake.
