Tibesti Mountains
Françoise Claustre (8 February 1937 – 3 September 2006), was a French archeologist who was taken hostage by a group of Chadian rebels, led by Hissène Habré, on 20 April 1974, at Bardaï, in the Tibesti Mountains of northern Chad. At the same time, the rebels also seized a German doctor, Christophe Staewen, and Marc Combe, who was an assistant of Claustre's husband, Pierre.
