(UN News Centre) – Thousands of Nigerians are escaping the deadly threat posed by the terrorist group Boko Haram and fleeing into neighbouring Cameroon, the United Nations refugee agency (UNHCR) has warned. In a press release, UNHCR cited Cameroonian authorities’ claims that some 13,000 Nigerian refugees had now crossed over from the Nigerian border state of Adamawa after Boko Haram insurgents attacked and captured the town of Mubi in late October. The refugees fled to the towns of Guider and Gashiga in the North region of Cameroon and to Bourha, Mogode and Boukoula in the Far North, the agency added.
