The abduction of more than 200 Nigerian girls by Boko Haram could be a turning point in the battle against Islamist militants, Nigeria's leader has said in an address to the World Economic Forum.

Meanwhile, the BBC has obtained footage in which some girls targeted by the kidnappers told how they had escaped.

One said she had hidden in a tree overnight, while another said she had fled after being put in a truck and taken into a forest.
