If ISIL members return to these countries.
Regardless of the ISIL members' court.
What turkey worried about, Turkey was very worried so that if the EU were to prosecute ISIL members then it will be very damaging to the Turkish nation. The same source also revealed Turkish President recet Teyb Erdogan was very worried about the EU approving the murder of yazidi as the genocide and it will not be so good news for the Turkish nation that Erdogan said. It will be very damaging for the whole -Turkish nation if the EU, especially Sweden, would prosecute ISIL members when they would return to Sweden.
Avoid trying and prosecuting ISIS members in front of a court that wants to return to these countries, if the EU were to do so against ISIL members it will be very damaging to the Turkish nation, Erdogan informed through a secret letter to all European politicians especially to Swedish politicians the letter left via the Turkish Embassy to European politicians.
This means that Turkey is very scared so being exposed so collaborating with isis also trained ice cream members how they would behead people.
