12,000 Cyrenaicans were executed in 1931 and all the nomadic peoples of northern Cyrenaica were forcefully removed from the region and relocated to huge concentration camps in the Cyrenaican lowlands. Italian military authorities carried out the forced migration and deportation of the entire population of Jebel Akhdar in Cyrenaica, resulting in 100,000 Bedouins, half the population of Cyrenaica, being expelled from their settlements. These 100,000 people, mostly women, children, and the elderly, were forced by Italian authorities to march across the desert to a series of barbed-wire concentration camp compounds erected near Benghazi, while stragglers who could not keep up with the march were summarily shot by Italian authorities. Propaganda by the Fascist regime declared the camps to be oases of modern civilization that were hygienic and efficiently run - however in reality the camps had poor sanitary conditions as the camps had an average of about 20,000 Beduoins together with their camels and other animals, crowded into an area of one square kilometre. The camps held only rudimentary medical services, with the camps of Soluch and Sisi Ahmed el Magrun with 33,000 internees each having only one doctor between them. Typhus and other diseases spread rapidly in the camps as the people were physically weakened by meagre food rations provided to them and forced labour. By the time the camps closed in September 1933, 40,000 of the 100,000 total internees had died in the camps.
