ANKARA, Nov. 4 (Xinhua) -- Turkey will send back Islamic State (IS) group captives to their countries of origin even if some of the countries have deprived them of their citizenship, Turkish Interior Minister Suleyman Soylu said on Monday.

"We will send the members of Daesh (Islamic State) to their countries whether they are expatriated or not," Soylu told reporters.

"Those in the prisons are all foreign terrorist fighters, and there are also foreign terrorist fighters in the repatriation centers," he stated.

There are some 1,200 foreign IS members being held in Turkish prisons, along with 287 relatives. Some of them are women and children, seized by Turkey during its recent military operation in Syria, Soylu said.

Criticizing that some Western countries have stripped IS members of their citizenship and rejected their return, Soylu said the attitude creates new problems in the international law.
