When Ahmad was 24-years-old he was shot twice, leaving him paralysed from the waist down. It was 2008, and he was living in his home country of Lebanon during the internal conflict between the Sunni and the Shia Muslims. Working as a paramedic at the time, Ahmad learned to live with his injuries until 2016 when he encountered a road block manned by the same man who had shot him eight years earlier.
