Tokyo Olympics organisers have reported 29 new games-related Covid-19 cases, including four athletes, reports Reuters.
Three of the four infected athletes are in the Greek artistic swimming team, the organisers said, without providing further details.
A spike in cases fuelled by the Delta variant this week led Japanese Prime Minister Yoshihide Suga to announce that only seriously ill Covid-19 patients would be admitted to hospital, raising fears of an increase in deaths.
The government has also signalled it might consider rolling back the controversial policy.
