A woman holds a sign to call for the release of more than 200 schoolgirls kidnapped by Boko Haram militants on May 19, 2014 during a sit-in organised by Human Rights organisations in Abidjan. The "#bringbackourgirls" slogan has become a huge global phenomenon following the abductions, albeit controversial, as world and opinion leaders get involved under its banner on social media to aggitate for the release of the girl-students by the islamist militants who continued their rampage by razing two schools in Bauchi state, northern Nigeria, where Boko Haram gunmen previously attacked a girls' school.
