Tribes are fighting over access to water for their horses and livestock
More than 250 people are dead following a week of battles on horseback between tribes in central Sudan who are fighting over access to water for their horses and livestock. The dead include 75 police officers who tried to intervene and stop the bloodshed. Shrinking amounts of water and grazing land is fueling conflict in Sudan and across the Sahel region of Africa as the Sahara desert expands southward.
