A Chibok schoolgirl who escaped from Boko Haram militants in Nigeria has called on the international community not to forget those still in captivity.

The girl who did not want her identity to be known told an education conference in Dubai that the international community should not forget about them.

Next month will mark the third anniversary of the abduction of more than 270 girls by Boko Haram militants.

The militants are still holding about 195 of the young women.

The abduction of the schoolgirls in north-eastern Nigeria in April 2014 by the islamist militant group caused a global outcry – and prompted campaigns about girls’ right to education.
