Rwanda armed Congolese rebels against Mobutu and Kabila

After butchering 800,000 people, the killers fled across the border into DR Congo (then known as Zaire).

Rwanda's new leaders wanted the Congolese dictator, Mobutu Sese Seko, to disarm the militias and were prepared to use force to get their way.

First they sent troops and engineered a rebellion to topple Mobutu. Then they invaded again in 1998 in an attempt to oust his successor, Laurent Kabila.
