Four guilty of plot to kill Rwandan general

Four men have been found guilty of trying to kill an exiled critic of President Paul Kagame. But two of the most high-profile suspects were cleared of all charges and released. Former Rwandan army general Kayumba Nyamwasa was shot outside his Johannesburg home in 2010. General Nyamwasa fled Rwanda in 2010 after falling out with President Kagame and was granted asylum in South Africa. The BBC's Nomsa Maseko reports from Johannesburg.
