Boko Haram is singling out geography teachers in its campaign of terror against Western education in Nigeria, it has been revealed.
Teachers of the subject have emerged as an unlikely top target for the group because their lessons contradict its bizarre world view on how the Earth was created.
Boko Haram believes that the Earth is flat rather than spherical, and that rainfall is caused not by evaporation, but by God's divine will.
As such, geography teachers are ranked alongside Nigerian security chiefs and senior politicians as prime candidates for assassination.
The threats to geographers are outlined in an extensive new report by Human Rights Watch, which lays bare the devastating impact wreaked by Boko Haram on Nigeria's school system.
