The Sentinelese Tribe
An indigenous tribe has lived on North Sentinel Island with limited contact from the outside world for the past 60,000 years. Anybody who has tried to contact the Sentinelese people has been killed, or at least drawn a violent reaction from the community. The island which rests in the Indian Ocean, is so dangerous for outsiders to attempt to visit that India’s government has established a three-mile exclusion zone to prevent more violence.
The tribe rejects modern civilization and actually prefers their no-contact status quo. Any visitors are attacked, from the two fishermen that lost their lives after fishing illegally within the exclusion zone to low-flying planes, the indigenous tribe is more than hostile towards outsiders. They violently rebut them. The 2nd picture in the above photo-set depicts a shipwreck which resulted in many deaths when the sailors clashed with the tribespeople. (Source)
