Chad: As army pursues rebels, militias fill vacuum

The stench of rotting corpses becomes unbearable. Locals say 75 of their men are buried in shallow graves in this glade on the village's outskirts, killed they say by men on horses, and by their own neighbours. The bodies were hastily buried in mid-May, days after a rag-tag group of men armed with guns, spears, and machetes overran the village in a dawn attack.
