Africa News Tonight: Saied dominates in Tunisia election, China drives into South Africa auto market, Kenyan runner suspended over drug test

Tunisia holds a presidential election Sunday that seems certain to give incumbent Kais Saied another term in office, with his main rivals jailed, disqualified or otherwise sidelined from the race. Chinese automakers are tapping into the South African car market, the largest on the continent, with prices so attractive that dealers say other brands risk being pushed to the curb. The Athletics Integrity Unit says Kenya's Emmaculate Anyango, the world's second fastest woman over 10 kilometers, has been provisionally suspended after a failed doping test.
