Türkiye hosts the largest number of refugees in the world—a total of four million refugees. Importantly, 1.7 million refugees were living in the provinces directly affected by the earthquake. Operating 30 detention facilities, Türkiye also has one of the largest immigration detention systems in the world. As well as designated detention facilities, it also detains non-nationals in ad hoc detention sites along its borders, airport transit facilities, and police stations. As of May 2022, there were more than 20,000 migrants and refugees detained across the country. Seven detention centres are located in the earthquake affected area: two in Adana, two in Malatya, one in Şanlıurfa, one in Gaziantep, and one in Hatay.
