This week on The Observers, a group of sub-Saharan migrants were left stranded in the desert at the Libyan border by Tunisian authorities. They captured videos of the experience, and one of them told us what it was like. Meanwhile, in Ivory Coast, a main thoroughfare between Guiglo and Tai turned to mud after heavy rains in the region. Our Observer Gaspard Goore Bi sent us videos of the situation as well as accounts from locals affected by the damage. Finally, a new rap song celebrates the Central African Republic capital of Bangui.
