Russian gymnast Ivan Kuliak is facing disciplinary proceedings by the International Gymnastics Federation (FIG) for displaying the letter "Z" on the podium next to a Ukrainian rival in Qatar.
But what does the symbol mean?
In Russia, the "Z" is fast becoming seen as a staunchly pro-war symbol of President Putin's invasion of Ukraine.

It has even been used by Serbs at pro-Russian demonstration in Belgrade. Photographs have been widely shared on social media.

"Often with propaganda the simplest things catch on the quickest," she says. "It looks rather intimidating and quite stark. From an aesthetic perspective, it's a very powerful symbol."
It has taken less than a fortnight for the "Z" to spread among those supportive of President Putin's invasion.
