Inside Nigeria’s centres for jihadists and their captives

On an arid plot of land in northern Nigeria, veiled women hurry past vegetable stalls and men idle outside endless rows of tarpaulin tents in what, at first glance, appears to be a typical camp for displaced people.
In reality, Hajj Camp in Borno State is a centre for processing tens of thousands of jihadists, their families and those who lived under their control. In exchange for freedom, the government persuaded them to turn themselves in — a move aimed at ending an insurgency by Boko Haram and the Islamic State West Africa Province (Iswap) group that has killed thousands and displaced over two million since 2009.
