There is no known policy of differential treatment of persons in detention on the basis of nationality, although according to observations from stakeholders, some Removal Centres detain specific population groups. For example, Izmir (Harmandalı), Kayseri, and Hatay detain mixed populations, including irregular migrants and foreign fighters, Gaziantep mostly holds Syrians classified as YTS (Foreign Terrorist Fighters).
In Izmir there is differential treatment for people who have been assigned a code compared to other irregular migrants, for example, there are restrictions on their right to make phone calls and go outdoors. The detention conditions of YTS are worse than other detainees and they are subject to arbitrary body checks and have limited rights to leave their cells. There have been claims of torture and ill-treatment.
