On the final day of his trip to the United States, Nigerian President Muhammadu Buhari vows to clean up his country's murky oil sector but calls on Washington to do more to help equip his troops in the battle against Boko Haram. Meanwhile, Burundi counts votes a day after its controversial presidential election. And parts of Cape Town plagued by gang culture are now looking to the very men who have caused the violence to teach younger generations how to tread a different path.
