The Kurdish-led Autonomous Administration courts began the prosecution of ISIS suspects after around 900 Syrian prisoners were referred to the People's Defense Court in Qamishli for trial.
Social Justice Council of North and East Syria member Khaled Ali said the court is currently looking into the cases of around 900 ISIS suspects accused of fighting or having links to the terrorist organization.
He said the laws applied in the trial are those included in Decree No. 20 that was issued by the Legislative Council of North and East Syria.
About 19,000 ISIS mercenaries, including 12,000 Syrians, are held in the Autonomous Administration prisons in northeast Syria.
On Saturday, the Autonomous Administration said all prisoners serving time for petty crimes, those suffering from incurable or terminal diseases and those aged over 75, will be released from prison.
However, the amnesty excluded people charged with betrayal, espionage, honor killing, sexual abuse, and trading with or consuming drugs, in addition to commanders in terrorist organizations like ISIS.
Ali called for establishing an international court to prosecute the foreign ISIS members held in the prisons of the Autonomous Administration that includes suspects from 55 countries. He said such courts would guarantee a fair trial and the implementation of international law that respects human rights.
Separately, around 20,000 Syrians prepare to be evacuated from al-Hol camp.
On Monday, a new batch of around 73 families consisting of 289 people from Deir Ezzor and its countryside left al-Hol.
Since early this year, around 5,000 Syrians from East Euphrates areas have been evacuated from the camp.
