Burundi is struggling to emerge from a civil war between Hutu rebels and the Tutsi-dominated government and army. Since fighting began in the early 1990s, it is estimated that one-in-six Burundians, or about 1 million civilians, were uprooted by the fighting. More than 300,000 were killed. Fears of genocide, a repeat of what happened in neighbouring Rwanda, have never been far from the surface.
