David Batenga, the nephew of Rwandan former intelligence chief Patrick Karegeya, has spoken about his shock upon finding his uncle dead in a hotel room.

"It was a state of disbelief... at first I just thought it was in a movie," Mr Batenga told the BBC.

Mr Karegeya, an exiled dissident, died in a Johannesburg at the beginning of January. South African police said at the time that it appeared he had been murdered.
