Deniz Naki, a Kurdish football player, has been barred from the Turkish Super League by the disciplinary council of the Turkish Football Federation (TFF), the NVT news portal reported.

The player is charged with spreading “separatist and ideological propaganda” in Turkey.

Naki was banned from all competitive matches for three years and six months, which equates to a lifetime ban in Turkey.

The 28-year-old Kurdish-German midfielder is a prominent supporter of Turkey’s Kurdish minority. He severely criticized the  Turkish military recent  operations in the Afrin region of Syria.

Naki was also detained in mid-summer due to the social media posts authorities find insulting President Recep Tayyip Erdogan.

Earlier, Naki was given suspended prison sentence of 18 months and 22 days due to his social media posts that the judge in charge claimed to be a part of terrorist propaganda. Naki said his postings aimed peace building in Turkey’s Kurdish regions in the east of the country, adding that he dedicated a 2016 win against rival Bursaspor to the people who lost their lives or got wounded during Turkish military operations in Diyarbakir’s Sur district.

“My statement following the match was the reason for them to file a complaint against me,” he told Turkish media. Turkey has intensified pressure against the Kurdish minority since the summer of 2015. While Kurdish majority cities were turned upside down with consecutive military attacks, hundreds of Kurdish politicians were jailed over terror charges.
