Demirtaş and Zeydan, who are both in prison in the northwestern province of Edirne, said they would go on hunger strike due to the actions of the Edirne prison warden.
A statement from Demirtaş released by the HDP on Thursday said: ” In consequence of the Edirne Prison’s stance of no-dialogue, unlawful practices, inhuman practices against other prisoners, and the complete lack of good intention regarding the ending of hunger strikes that have been continuing for days, we, too, from Friday on, will begin a hunger strike. We invite the public to display sensitivity regarding the hunger strikes and violations of rights continuing in prisons.”
The HDP is the second largest opposition party in Turkey and fiercely against the constitutional changes.
Demirtas has been in jail along with the HDP’s co-leader Figen Yuksekdag and 11 other lawmakers of the party on accusations of links to Kurdish militants.
Demirtas and the HDP have denied the allegations and accused the government of using a state of emergency introduced after a failed coup last year to suppress dissent.
