Interior Minister Suleyman Soylu had warned last week that Ankara would begin to send back Islamic State militants to their home countries on Monday even if their citizenships have been revoked.
"One American foreign terrorist fighter whose proceedings are completed has been deported," ministry spokesman Ismail Catakli was quoted as saying by the state-run Anadolu news agency.
"Travel plans for seven foreign terrorist fighters of German origin at deportation centers have been completed, they will be deported on Nov. 14," he added.
