 The government-supported Janjaweed were accused of committing major human rights violations, including mass killing, looting, and systematic rape of the non-Arab population of Darfur.They have frequently burned down whole villages, driving the surviving inhabitants to flee to refugee camps, mainly in Darfur and Chad; many of the camps in Darfur are surrounded by Janjaweed forces.By the summer of 2004, 50,000 to 80,000 people had been killed and at least a million had been driven from their homes, causing a major humanitarian crisis in the region.
