Olympic athletes have received an extra incentive for winning a medal after organisers said they could remove their masks for 30 seconds for photos on the podium.
Medal-winners were urged not to abuse the relaxation in the rules at the Tokyo Games, which have been marked by their strict anti-coronavirus measures after opening a year late.
