It’s been 600 days since over 200 abducted Nigerian schoolgirls  have been in the hands of their captors, Boko Haram.

The girls were seized from their school in Chibok; a community in the north eastern state of Borno. The report of their abduction had spurred worldwide protest by campaigners calling for their release.

There are rising fears that Boko Haram has been using some teenage girls to detonate explosive in soft targets.

The girls were abducted by the Islamist extremist group in April 2014, raising worldwide uproar.
