Nobel Peace prize winner, Malala Yousafzai, has called on Nigeria to intensify efforts to free 219 schoolgirls who were abducted by Islamist militants six months ago.
The 17-year-old Pakistani girl said campaigners needed to raise their voices “louder than ever” to demand the freedom of the girls.
Foreign governments including the US and China, have sent experts to Nigeria to help track them down.
Boko Haram fighters abducted the girls during a raid on their boarding school in Chibok town in north-eastern Nigeria in April.
Malala said in a statement that the schoolgirls needed to be reunited with their families and receive a quality and safe education.
“I urge the Nigerian government and the international community to redouble their efforts to bring a quick and peaceful conclusion to this crisis,” Malala said.
Critics accuse government of not doing enough to secure the release of the girls – a charge ministers deny.
