During most of the civil war, the FRELIMO-formed central government was unable to exercise effective control outside of urban areas, many of which were cut off from the capital. RENAMO-controlled areas included up to 50% of the rural areas in several provinces, and it is reported that health services of any kind were isolated from assistance for years in those areas. The problem worsened when the government cut back spending on health care. The war was marked by mass human rights violations from both sides of the conflict, with RENAMO contributing to the chaos through the use of terror and indiscriminate targeting of civilians. The central government executed tens of thousands of people while trying to extend its control throughout the country and sent many people to "re-education camps" where thousands died.
