South Africa has recalled its ambassador to Rwanda following a diplomatic row over the shooting of an exiled Rwandan general in Johannesburg. Gen Faustin Kayumba Nyamwasa, a critic of Rwandan President Paul Kagame, was shot and wounded in June. South Africa said it had not broken diplomatic ties and no connection was being made between the ambassador's withdrawal and the shooting. Rwanda denies any involvement in the shooting of the general. Rwanda summoned South Africa's ambassador to Kigali, Gladstone Dumisani Gwadiso, last month to discuss the investigation into Gen Nyanwasa's shooting.
