Premise: The area is used by both nomadic herders, who follow their herds and stay in mobile cattle camps, and sedentary farmers. "Attacks in this region could be the work of the (Tuareg rebel) Niger Justice Movement (MNJ) or they could be the work of Malian bandits," a security source, who declined to be identified, told Reuters. The rebels say that wealth generated from Niger's vast uranium deposits has not been distributed equally, and demand more autonomy for the Tuareg inhabitants of the northern Agadez region, where most of Niger's uranium is mined. At least 300 rebels and 80 government soldiers have been killed since the MNJ began its military campaign in early 2007.
Hypothesis: The farmers in the area don't move around.
