During his decade in charge of intelligence, Rwanda was involved in complex fighting both internally and in the eastern Zaire (now Democratic Republic of the Congo). Many Hutu, both Interahamwe (the group most responsible for the genocide) and innocent civilians, were packed into refugee camps on the Zaire-Rwanda border. This led to the creation of a large variety of militia groups being backed by different regional powers in the First and Second Congo War. Karegeya had a large role in coordinating intelligence for these wars and for dissident suppression at home.
