Inside the refugee camps as Nigerians flee Boko Haram

More than two million Nigerians have fled their homes seeking refuge from Boko Haram insurgents over the last six years.

One of the largest camps is in a semi-arid field outside the north-eastern town of Dalori, with row upon row of white tents stretching for more than a kilometre.

BBC Africa's Jimeh Saleh met some of the 18,000 residents there and heard how they have survived attacks by the Islamist militant group.
