Throughout the 1990s, Médecins Sans Frontières (MSF) was forced to face the challenges posed by the genocide of Rwandan Tutsis and a succession of outbreaks of political violence in Rwanda and its neighbouring countries. Humanitarian workers were confronted with the execution of almost one million people, tens of thousands of casualties pouring into health centres, the flight of millions of people who had sought refuge in camps and a series of deadly epidemics. Drawing on various hitherto unpublished private and public archives, this book recounts the experiences of the MSF teams working in the field. It is intended for humanitarian aid practitioners, students, journalists and researchers with an interest in genocide and humanitarian studies and the political sociology of international organisations.
