Archaeologists said Tuesday they had discovered the remains of victims from a 6,000-year-old massacre in Alsace in eastern France that was likely carried out by "furious ritualized warriors".

The corpses of 10 people were found outside Strasbourg in one of 300 ancient "silos" used to store grain and other food, a team from France's National Institute for Preventive Archaeological Research (Inrap) told reporters.

The Neolithic group appeared to have died violent deaths, with multiple injuries to their legs, hands and skulls.

The way in which the bodies were piled on top of each other suggested they had been killed together and dumped in the silo.

"They were very brutally executed and received violent blows, almost certainly from a stone axe," said Philippe Lefranc, an Inrap specialist on the period.
