Former national boxing champion Shaaban Kattan leads a training session at the Shahba boxing club. He founded the club in Syria's war-torn city of Aleppo in the summer of 2015.

Boys line up and mimic Kattan, who became Syria's national champion only one year after taking up boxing professionally in 1994. Kattan opened the club with colleague Ahmad Mashallah to improve their form, and to give young fighters a chance to learn.
