Shot Pakistan schoolgirl Malala Yousafzai addresses the UN

Few teenagers have made such a worldwide impact as Malala Yousafzai the Pakistani teenager who was shot in the head by the Taliban last October for campaigning for girls' right to education.

After being flown to Britain for surgery she has since made a remarkable recovery and now, on her 16th birthday, she has addressed the United Nations in New York.

She called for world leaders to provide better access to education for children and young people everywhere.
