A French journalist recounts 711 days of captivity as a hostage of Islamic extremists in Mali

Olivier Dubois, a French journalist, was kidnapped by JNIM, a branch of al-Qaida in Africa's Sahel region, while on his way to interview one of the group's leaders in northern Mali. He spent 711 days in captivity, sleeping chained to a tree, eating dried goat meat and plotting his escape. Twenty-two months after his liberation, he recounts his experiences in a book that was released on Thursday in France.
