Party leaders Selahattin Demirtas and Figen Yuksekdag, who were detained overnight during a terror investigation, were today remanded in custody by a court in the southeastern city of Diyarbakir.
They will be held behind bars pending trial, although no date has been set yet.
A total of 12 HDP parliamentarians were rounded up overnight in an unprecedented crackdown on the party, which has sparked international alarm.
As well as Demirtas and Yuksekdag, five other MPs were also remanded in custody following hearings in Diyarbakir and in other cities.
Another three HDP lawmakers -- Ziya Pir, Imam Tascier and Sirri Sureyya Onder -- were allowed to go free under judicial control, the Turkish equivalent of bail.
Court hearings for two others, Ferhat Encu and Abdullah Zeydan, were ongoing.
