Turkish prosecutors seek a prison sentence of from 8 to 27,5 years for two university students on the grounds that they chanted pro-Kurdish slogans and sang a pro-Kurdish guerilla anthem during a demonstration in Diyarbakır province, the Gazete Karınca reported.

The indictment, prepared by the Diyarbakır Public Prosecutor’s Office, accused the students of disseminating propaganda on behalf of the Kurdistan Workers’ Party (PKK), as well as provoking people to hatred, revenge and enmity and insulting state authorities.

Turkey has stepped up its crackdown on Kurdish politicians in recent months. Trustees have been appointed to dozens of municipalities in the country’s predominantly Kurdish Southeast, while hundreds of local Kurdish politicians as well as 11 HDP deputies including the party’s co-chairs are behind bars on terror charges.
