"We've been flooded here in Mora by Cameroonians and Nigerians fleeing Boko Haram," a police officer in the northern town told AFP on condition of anonymity.
"The day before yesterday, there were already more than 10,000 people in Mora. Not a day goes by without more people coming."
The number of internally displaced people in Nigeria and those who have crossed its borders into Cameroon, Niger and Chad because of the militant violence has been increasing, with no end sight to the insurgency.
The United Nations' humanitarian office (OCHA) said on August 5 that Boko Haram attacks have forced nearly 650,000 people from their homes in the northeast states of Borno, Yobe and Adamawa.
