The stories behind the news. In this edition: the government in Tanzania warns of the dangers of black magic as the country prepares to go to the polls in October; how the presence of militants in Egypt's Sinai peninsula, who are allied to the so-called Islamic State, marks an ominous turn for the authorities in Cairo; in the Czech Republic there's a plan to extend overcast mining in what was once a largely-undisturbed landscape of pine forests and deep valleys -- and it could have severe consequences for some of the people living there; an island community pulls together as a medical emergency descends on distant Tristan da Cunha, six days' sail away from specialist health treatment. And the music, the cars, the sunshine and the history - they're all part of the daily drive to work enjoyed by our man in the Cuban capital, Havana.
