The United Nations has warned that increasing violent unrest in eastern Democratic Republic of the Congo may spark a huge increase in the numbers of people fleeing the fighting.
More than 160,000 people have already been displaced this year in the region's North Kivu province.
Aid agencies believe a further 280,000 people may flee in the next six months.
The instability, which involves dissident Congolese troops and Rwandan rebels, has seen villages attacked by armed groups that loot, rape and kill.
