IDPs estimated that 1,538,982 people forced to flee their homes in Nigeria were still living in internal displacement camps. This figure includes people displaced as a result of brutal attacks by the Islamist armed group Boko Haram in north-eastern Nigeria, the government-led counterinsurgency operations against the group, ongoing inter-communal clashes and natural hazard-induced disasters. The in
crease in the first half of 2015 of the number of internally displaced people (IDPs) in Nigeria was due to ongoing violence in the north-east as well as the return of refugees who have not been able to settle back in their places of origin and are therefore considered as IDPs. The biggest rise in the number of IDPs was registered in Borno state, one of the three north-eastern states most affected by Boko Haram violence, followed by Adamawa and Yobe.
