Turkish Interior Ministry spokesman Ismail Catakli said that a pair of German and Danish nationals would also be deported later on Monday while seven German nationals would be returned on Thursday. Cataki did not immediately provide further information on the IS suspects but said they were being held in deportation centers.

Turkish Interior Minister Suleyman Soylu said about 1,200 foreign IS fighters were in Turkish prisons and more than 280 members, including women and children, were re-captured during Turkey’s military offensive into northeast Syria last month.
