December 2015 marks 20 years since the Dayton Accords brought an end to the Balkan war. Today, Bosnia is still struggling to rebuild and has been hurt by divisions that run deep.

In a nation still divided along ethnic lines, their example stands out as a tragic exception. Report by Luke Brown, Alexandra Renard and Mersiha Nezic.
