Sentinelese

The Sentinelese, also known as the Sentineli and the North Sentinel Islanders, are an indigenous people who inhabit North Sentinel Island in the Bay of Bengal in India. They are considered one of the world's last uncontacted peoples. Designated a Particularly Vulnerable Tribal Group and a Scheduled Tribe, they belong to the broader class of Andamanese people.

Along with the Great Andamanese, the Jarawas, the Onge, the Shompen, and the Nicobarese, the Sentinelese are one of the six native and often reclusive peoples of the Andaman and Nicobar Islands. Unlike the others, the Sentinelese appear to have consistently refused any interaction with the outside world. They are hostile to outsiders and have killed people who approached or landed on the island.[1]

In 1956, the Government of India declared North Sentinel Island a tribal reserve and prohibited travel within 3 miles (4.8 km) of it. It further maintains a constant armed patrol to prevent intrusions by outsiders. Photography is prohibited.

There is significant uncertainty as to the group's size, with estimates ranging between 15 and 500 individuals, but mostly between 50 and 200.
