The Summer Paralympic Games get underway in Paris today. More than 4,000 athletes from all around the world will meet in the French capital to compete in 22 sports across 549 different events. Delegations from 184 nations will parade down the iconic Champs-Élysées to the Place de la Concorde rather than entering a stadium. The first official Paralympic Games were held in Rome in 1960. Twenty-three nations took part, competing in eight sports, including wheelchair basketball and para-athletics.
