Gymnast Ivan Kuliak caused outrage on Saturday by wearing a Russian war symbol on his shirt while sharing a podium with a Ukrainian rival.
Former Russian junior champion Kuliak had just finished third behind winner Ukraine's Illia Kovtun in the parallel bars at a World Cup event in Doha.
And as the gymnasts were pictured standing shoulder to shoulder to collect their medals, clearly visible was a letter 'Z' taped across the middle of Kuliak's shirt.
The letter Z, which symbolically represents 'victory' in Russian, is daubed on to the front of
Vladimir Putin's tanks and other military vehicles.
