Angelina Jolie-Pitt, the UN refugee agency’s special envoy, says that the number of people left homeless by conflict in Africa is increasing.

Speaking in London as part of the BBC’s World on the Move special coverage, she said:

“In the past six years, 15 conflicts have erupted or re-ignited. The average time a person will be displaced is now nearly 20 years.

“The number of refugees returning to their homes is the lowest it has been in three decades. Africa has more people displaced than ever before.
