French scientists working in collaboration with the British Museum have been examining dozens of skeletons, a majority of whom appear to have been killed by archers using flint-tipped arrows.

The bones – from Jebel Sahaba on the east bank of the Nile in northern Sudan – are from victims of the world’s oldest known relatively large-scale human armed conflict.

Over the past two years anthropologists from Bordeaux University have discovered literally dozens of previously undetected arrow impact marks and flint arrow head fragments on and around the bones of the victims.
