Rare footage of the "uncontacted" tribe that killed the missionary who illegally went to their island to preach

The Sentinelese are one of the world's last "uncontacted" indigenous peoples, a hunter-gatherer tribe who live on the remote North Sentinel Island in India's Andaman Islands chain. You may recall that last November, a missionary named John Allen Chau, 27, obsessed with trying to convert the tribe to Christianity, paid local fishermen to help him get near the island. As soon as he illegally landed his canoe on the shore and started preaching, the Sentinelese fired arrows. He escaped with injuries but returned twice later and was eventually killed.

This footage above of the Sentinelese from 1991 was taken by anthropologist T N Pandit of India's Ministry of Tribal Affairs who attempted to visit them for several decades. Usually, the Sentinelese hid or fired arrows, but in 1991 they waded into the ocean to meet Pandit and his team peacefully.

"We were puzzled why they allowed us," he told the BBC last year. "It was their decision to meet us and the meeting took place on their terms."

"We jumped out of the boat and stood in neck-deep water, distributing coconuts and other gifts. But we were not allowed to step onto their island."

According to the BBC, "Mr Pandit says he does favour the re-establishment of friendly gift-dropping missions with the tribe, but says they should not be disturbed. 'We should respect their wish to be left alone, he said.'"

Well, duh.
