Turkey has sent more than 6,000 Syrian migrants in Istanbul to temporary housing centres in other provinces since early July, the local governors office said on Friday, two weeks after a deadline for Syrians not registered in the city to leave. Authorities had given Syrians not registered in Istanbul until Oct. 30 to move to another province or face forced removal from the city, Reuters reported. Turkey hosts more than 3.6 million Syrians, the largest population of Syrians displaced by an eight-year civil war. The number of Syrians in Istanbul, a city of some 15 million, has swelled to more than half a million. The Istanbul governors office said 6,416 unregistered Syrians were removed from Istanbul since July 12. According to Reuters, sentiment towards Syrian refugees in Turkey has soured in recent years. Ankara wants to settle part of them in a swathe of land it now controls in northeast Syria, after it launched an offensive last month against the Kurdish YPG. Amnesty International and Human Rights Watch last month published reports saying Turkey is forcibly sending Syrian refugees to northern Syria. However, Turkeys Foreign Ministry called the claims in the reports "false and imaginary." The governors office also said it had sent 42,888 illegal migrants to provinces that have repatriation centres, adding that their deportation process is continuing in those centres.
