Iranian Para-cyclist Bahman Golbarnezhad has died following an accident during men’s C4/C5 road race at the Rio 2016 Paralympics. He was involved in a serious crash on Saturday (17 September) and sustained severe injuries to his neck. The 48-year-old rider received emergency treatment at the scene before being transported to hospital where he succumbed to his injuries. Following Golbarnezhad's passing, the Iranian flag has been lowered to half-mast in the Paralympic Village. The Paralympic flag will also be flown at half-mast in the Paralympic Village and at the Riocentro venue, where Iran played Bosnia and Herzegovina in the sitting volleyball gold medal match on Sunday (18 September).

Every participant at the Paralympics has their disability grouped into one of five disability categories; amputation, the condition may be congenital or sustained through injury or illness; cerebral palsy; wheelchair athletes, there is often overlap between this and other categories; visual impairment, including blindness; Les autres, any physical disability that does not fall strictly under one of the other categories, for example dwarfism or multiple sclerosis. Each Paralympic sport then has its own classifications, dependent upon the specific physical demands of competition. Events are given a code, made of numbers and letters, describing the type of event and classification of the athletes competing. Some sports, such as athletics, divide athletes by both the category and severity of their disabilities, other sports, for example swimming, group competitors from different categories together, the only separation being based on the severity of the disability.
