In the DRC, there are wars both between Congolese and conflicts with neighboring nations. Although these wars have components of intertribal conflict, in several cases the conflicts have been induced by external forces, such as changes in international support and foreign aid, and demand for resource extraction. As a result of tantalum mining and wars, societies in the eastern regions of the Congo are experiencing heightened physical and economic insecurity, health problems and human-rights violations. In the Ituri region, a violent conflict is occurring between the Lendu and the Hema tribes. Analysts have determined that the conflict has intertribal as well as economic components brought about by the patterns of coltan extraction.
