The National Prosecuting Authority says four men found guilty of an attempt to murder an exiled former Rwandan general in South Africa were sentenced to eight years in jail.

South Africa's Kagiso Magistrate's Court on Wednesday sentenced a Rwandan and three Tanzanians to eight years for attempted murder, five years for possession of an unlicensed firearm and two years for possession of illegal ammunition. Spokesman Nathi Mncube said the sentences would run concurrently.

Two other suspects had earlier been acquitted for the 2010 shooting that injured Gen. Faustin Kayumba Nyamwasa.

Nyamwasa, a former top aide to Rwanda's president, fell out with him and fled to South Africa where he was granted political asylum. Nyamwasa accuses Rwanda's president of ordering attempts on his life.

Rwanda's government denies involvement in the attacks.
