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, İzmir (Harmandalı), Kayseri, and Hatay detain mixed populations, including irregular migrants and foreign fighters, Gaziantep mostly holds Syrians classified as YTS (Foreign Terrorist Fighters).
In İzmir 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.
In İstanbul there are reports of discrimination especially against Afghan and Pakistani nationals who do not get released as easily. The deportation procedure is reportedly executed much faster for Afghan nationals. The situation of sex workers is also problematic. A Turkmen national was accused of being a sex worker and was held in the removal centre for one year, before being released due to the COVID-19 outbreak. There is also discrimination against people suspected of a crime who find it more difficult to get a positive decision from the administrative courts.
