 Millions of Hutu fled as refugees, contributing to large refugee camps of Hutu in the neighboring Democratic Republic of the Congo, where there were already refugees from other countries.These were disbanded by an RPF-sponsored invasion in 1996 that replaced the new Congolese president as the result of the First Congo War.A second invasion to replace the new Congolese president initiated the Second Congo War, the deadliest war since World War II and one involving many African nations including Rwanda for many years to come.
