Violent conflict erupted in Equateur province, western Democratic Republic of the Congo (DRC) in 2009, leading to the displacement of 200,000 people and hundreds killed. The conflict has its roots in long-standing economic and political grievances between the Boba and Lobala tribes. Control over the key commercial town of Dongo led to major violence in October 2009, when a Lobala militia attacked the local population, targeting Bobas in particular.
