Africa Calling podcast looks at some of the week's top stories from the African continent, including reports from the field and analysis with regional experts. This week we’re talking about the controversy surrounding the slaughter of villagers in Mali. We look into why 105 people were killed in Niger, and upcoming Uganda elections. Our DRC correspondent speaks about ex-militia leader Roger Lumbala, and why he was arrested in Paris. We also hear from the Kiswahili service on back-to-school in Kenya, and the fallout after Interpol dropped an arrest warrant in Guinea Bissau.
