Police in South Africa have begun a murder investigation into the death of a leading Rwandan opposition figure.

Patrick Karegeya, whose body was found in a hotel room in Johannesburg, may have been strangled.

The former intelligence chief fled Rwanda after he was accused of plotting against his former ally, President Paul Kagame in 2006.

Peter Biles reports from Johannesburg.
