TOKYO: Tokyo Olympics organisers said on Saturday (Aug 7) they have so far issued severe warnings to 16 individuals and revoked the accreditation of several people for breaking the Games' COVID-19 guidelines.Hidemasa Nakamura, chief of Tokyo 2020's main operation centre, told reporters the accreditation of eight individuals had been revoked and those of another eight paused.Though organisers did not provide details on the individual cases, they said each case was discussed with the International Olympic Committee and other relevant organisations."It was difficult to both carefully and speedily proceed, but I believe we have been successful (in enforcement)," said Nakamura.The Tokyo 2020 Olympics is taking place as Japan is fighting a resurgence of the coronavirus, with cases reaching a grim milestone of 1 million on Friday, according to local media.Athletes and other officials who have travelled to Japan to participate in the Games are tested frequently and are confined to their "bubble", which prevents them from interacting with the wider Japanese public and potentially spreading the virus.The participants' adherence to the organisers' "playbooks" - sets of guidelines to prevent the transmission of the virus - is of particular importance as Tokyo grapples with a spike in coronavirus cases.
