According to the London Telegraph, "one of the world's last Stone Age tribes" has killed two fisherman who strayed into its territory:
The Sentinelese, thought to number between 50 and 200, have rebuffed all contact with the modern world, firing a shower of arrows at anyone who comes within range.
They are believed to be the last pre-Neolithic tribe in the world to remain isolated and appear to have survived the 2004 Asian tsunami….
Environmental groups urged the authorities to leave the bodies and respect the five-kilometre exclusion zone thrown around the island.
While it helps to have the local greens on your side, the Sentinelese have other ways to protect their sovereignty. The Telegraph reports that "The Indian coast guard tried to recover the bodies using a helicopter but was met by a hail of arrows."
