Midjiyawa Bakary, governor of Cameroon's Far North region, says authorities have also arrested hundreds of Cameroonians and Nigerians accused of collaborating with Boko Haram.
He said they deported Nigerians who said they were refugees but were not staying at refugee camps and did not have identification papers.
Bakary said today that women, children and men were taken to Nigeria's Sahuda village in Mubi, along the border. In Nigeria, many said they were forced to flee quickly over the weekend.
