Thirty-seven people were detained in the provinces' Cizre district as part of an operation against the KCK and were questioned by police. All of the detainees were referred to a court for arrest after they were questioned further by a prosecutor. The court arrested 31 suspects and released the remaining six pending trial.
The KCK investigation started in December 2009 and a large number of Kurdish politicians, including several mayors from the pro-Kurdish Peace and Democracy Party (BDP), have been detained in the case. The suspects are accused of various crimes, including membership in a terrorist organization, aiding and abetting a terrorist organization and attempting to destroy the country's unity and integrity. The suspects include mayors and municipal officials from the pro-Kurdish BDP.
