Mohammed Abu Amar runs a makeshift 24-hour helpline from his flat in Hamburg, guiding scared refugees fleeing the violence in Syria across the water to Europe.
Despite losing the use of both legs in a shelling in Damascus in the early days of the conflict, Abu Amar made the crossing with his family in 2013. He subsequently found his calling, being constantly available on the phone for his fellow Syrians making the same perilous journey.
