Several dozen people, almost all women and children, sheltering under a couple of large trees opposite the IDP camp's entrance, on the other side of the road. They were hungry and desperate and had been waiting for six days to be let into the camp. The families were from the Fulani tribe, nomadic cattle herders widely dispersed across the Sahel and West Africa. Their men had been killed, their cattle stolen. Half of the children with them were orphans. Inside the camp more recently arrived families were waiting for assistance. There wasn't enough room in the camp to accommodate them and authorities were scrambling to organise assistance. The families had come from a camp across the border in Cameroon where they had previously fled to from Nigeria. A lack of food and increased insecurity had driven them back.
