UEFA has launched an investigation against Turkey's hero in the match against Austria. What is it?

After the match between Austria and Turkey, Turkish defender Merih Demiral became a hero for his team by scoring a double. But the centre-back's unsportsmanlike actions came to the attention of UEFA.

According to the organisation's website, an investigation has been launched into the defender due to his likely inappropriate behaviour. The essence of the claims in UEFA do not disclose, but during the match, Demiral showed a gesture that can be called as a "wolf salute".

He posted a picture of the gesture, which is, incidentally, banned in Austria, on his Instagram and accompanied it with the unofficial slogan of Turkish nationalists "how happy is the one who can call himself a Turk".

The gesture itself is associated with the Bozkurt ("Grey Wolves") organisation, the far-right and radical wing of the Nationalist Movement Party, whose main tenets are the ideas of Turkish nationalism and pan-Turkism (unification of Turkic peoples).

It is not yet known what punishment Demiral may face.
