Michelle Obama, Malala Yousafzai and Hillary Clinton are just a handful of the many celebrities urging government forces to use military intervention in order to get the girls home safely.
The girls were taken on 14 April 2014 from their school in north-east Nigeria by Boko Haram, a terrorist group whose name means 'western education is forbidden/sinful' and who oppose the education of girls.

The girls' school had reopened to allow the girls to take their final exams. This decision was amid security concerns, which saw many schools in the same state remaining closed.
While some of the kidnapped girls have escaped, many are still being held, and reports suggest some girls are being sold into forced marriage.
Family members of the kidnapped girls formed makeshift search parties and Nigerian police are offering a £300,000 reward for help finding the girls - but so far, there have been no advances.
