Video - More than 670,000 Nigerians living in camps due to insurgency
The eight-year Boko Haram insurgency in Nigeria's northeast has displaced around 2 million people, some in Nigeria and some overseas. The United Nations calls it one of the world's worst humanitarian crises. More than 670,000 of those people live in camps in Nigeria's northeast. Their story is one of despair and one that tell of a longing of returning to their home towns. Leslie Mirungu reports.
