Pro-Kurdish People’s Democratic Party (HDP) Adana deputy Meral Danış Beştaş said she is being kept under tight isolation in the prison.

As part of a parliamentary question she submitted from Silivri prison, Beştaş said she has been kept under solitary confinement for the past 15 days.

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 have been arrested on terror charges.

Turkey currently keeps 11 HDP deputies including the party co-chairs Selahattin Demirtaş and Figen Yüksekdağ behind bars.
