Nigerian refugees are “too traumatized to return” anytime soon, according to a senior official from the UN humanitarian affairs office (OCHA), talking to UN News on the border with Cameroon.

Around 35,000 have fled from extremist violence in the northeast Nigerian town of Rann, in just the past two weeks, with dozens killed during a largescale Boko Haram assault two days ago, although Nigerian forces have reportedly taken back control, said OCHA’s Jean-Sébastien Munié.

Daniel Dickinson was at the border for UN News on Friday, and began by asking Mr. Munié to describe the scene around them.
