I’m incredibly skeptical of this story simply because of a Universiy teacher of mine who furiously claimed to us that cannibalism was a racist myth invented by evil British Imperialists. He was, I think, inspired by the book “The Man-Eating Myth: Anthropology and Anthropophagy” by William Arens. However, a quick glance at the cannibalism wikipedia page suggests the debate may have moved on since the late 90′s and I assume it will be attened to further in the comments section of this piece.
In short it appears that France 24 are reporting an act of cannibalism as a weird form of vigilante behaviour amid what sounds like continuing mob rule and civil war in the region:
