Officials have been quoted as saying as many as 500 undocumented Afghan migrants try to enter Turkey every day.
Nearly 20,000 undocumented Afghan migrants have arrived in Turkey in the past week three months, an unprecedented number according to the latest figures from the Turkish General Directorate of Security, the Hürriyet Daily News reported.
The report said that a total of 17,847 undocumented Afghan migrants have been captured by security forces from the beginning of 2018 until March 29.
The same period has seen 9,426 Syrian migrants, 5,311 Pakistani migrants and 4,270 Iraqi migrants.
Nearly 500 undocumented Afghan migrants try to enter Turkey per day, which has prompted security forces to examine the case in detail, Hürriyet Daily News reported.
As part of the investigation, the Directorate of Anti-Human Trafficking has been established in the eastern province of Erzurum, a hotspot used by migrants to go to Istanbul.
