Scientists are investigating what may be the oldest identified race war 13,000 years after it raged on the fringes of the Sahara.

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.
