In tonight's programme we begin in the east of the Democratic Republic of Congo, where children have died after a school fire broke out in the M23 rebel occupied city of Bukavu. Also, Senegal looks to the skies as it seeks to develop its home-grown satellite industry. And finally, we wonder about the future of African cities. How will they cope with the population boom and climate crisis? A question, the Kenya architecture biennale in Nairobi tried to answer.
