Buhari inauguration: Nigerian president sworn in for second term

Nigerian President Muhammadu Buhari is sworn in for a second term in a low-key ceremony. He will have the daunting task of managing Nigeria's unemployment rate. We hear from our correspondent in Abuja. We also take a look at Eritrean migrants who fled violence in their home country and are now facing the hardships of makeshift camps in the French capital. And we meet the writer of "Little Africa", a book and a city guide for the best of African culture in Paris.
