A Rwandan ex-general who has survived two assassination attempts says the man who was last seen with the ex-spymaster killed in a South African hotel was a Rwandan businessman who befriended the victim in a Rwandan jail.

Police say former Col. Patrick Karegeya's body, apparently strangled, was found Wednesday in Sandton's Michelangelo Towers hotel along with a bloodied towel and rope.

Former Lt. Gen. Kayumba Nyamwasa said Saturday that Karegeya was last seen by a family member at the hotel with Apollo Ismael Kisiriri.

Nyamwasa said he had twice met Karegeya with Kisiriri and that "he (Karegeya) trusted him absolutely ... but now one is dead."

Exiled opponents accuse Rwandan President Paul Kagame of ordering Karegeya's assassination and 2010 attempts on Nyamwasa's life in the South African city of Johannesburg.
