Over July, Cameroon has repatriated an estimated 3,500 undocumented Nigerian asylum seekers towards Adamawa state. Another 12,000 are stranded at the Nigeria/Cameroon border in Adamawa state. They can be expected to be repatriated throughout August and are in urgent need of further assistance. Cameroon’s decision follows a series of Boko Haram attacks in Cameroon; Cameroonian authorities claim the militants have entered the country disguised as refugees. Significant shelter and WASH needs have been reported for returnees in Adamawa and Borno states. The current level of response is reportedly not covering basic needs and should be scaled up ahead of the expected additional arrivals.
