This seems like a good follow up on my review of the book "War Before Civilization". From the Telegraph:
One of the world's last Stone Age tribes has murdered two fishermen whose boat drifted on to a desert island in the Indian Ocean.
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.
The two men killed, Sunder Raj, 48, and Pandit Tiwari, 52, were fishing illegally for mud crabs off North Sentinel Island, a speck of land in the Andaman and Nicobar Islands archipelago.
During the night their anchor, a rock tied to a rope, failed to hold their open-topped boat against the currents and they drifted towards the island.
"As day broke, fellow fishermen say they tried to shout at the men and warn them they were in danger," said Samir Acharya, the head of the Society for Andaman and Nicobar Ecology, an environmental organisation.
"However they did not respond - they were probably drunk - and the boat drifted into the shallows where they were attacked and killed."
Efforts to recover the bodies were unsuccessful.
