A prominent Rwandan exile who was shot in South Africa alleges his president was behind a plot to kill him, and that the leader has tried to kill other dissidents around the world.

Kayumba Nyamwasa, once a top military aide to Rwandan President Paul Kagame, spoke to The Associated Press in an exclusive interview Thursday after finishing his testimony as a witness in the trial of six East Africans accused of attempted murder in his 2010 shooting. Rwanda's government has denied involvement in an attack that left Nyamwasa with a bullet lodged at the base of his spine.

Nyamwasa says, "there's no doubt that my life has been threatened by the president of Rwanda."

Nyamwasa also accuses Kagame of fueling a rebellion in Congo, in order to keep Rwanda's giant, mineral-rich neighbor weak.
