Şebnem Korur Fincancı, the head of Turkey’s doctors’ union, was sent to prison by a court on Thursday, according ot the Turkish media.

Fincancı, 63,  was initially detained at her home in İstanbul on Wednesday on allegations of spreading “terrorist propaganda” after she urged a probe into the army’s alleged use of chemical weapons against Kurdish militants,

She is a forensic expert and a prominent human rights activist.

The Ankara Chief Public Prosecutor’s Office launched an investigation into Fincancı on charges of disseminating terrorist propaganda and insulting the state due to her remarks about the Turkish Armed Forces’ (TSK) alleged use of chemical weapons against militants from the outlawed Kurdistan Workers’ Party (PKK) in Iraq. Fincancı said she had examined video images and called for a probe.

Turkey has strongly rejected the allegations that appeared in media outlets close to the PKK that its army was using chemical weapons in its counterterrorism operations in northern Iraq.

The PKK is listed as a terrorist group by Turkey and much of the international community.
