Turkish authorities detained 81 people, most of them foreigners, on Thursday on suspicion of planning to travel illegally to join Daesh terrorists in Iraq and Syria.
Of those detained, 21 were suspected of being senior figures in the Daesh network, who were in charge of recruiting new militants, providing logistical support and helping with the medical care of wounded Daesh terrorists.
The remaining 60 were foreign nationals, of which 20 were minors, who were to be sent to Iraq and Syria.
Authorities said the operation was centered in Istanbul but involved raids at 31 locations in six Turkish provinces. A total of 31 addresses were raided in the operation.
Numerous passports and identity cars, two handguns, 200 bullets, military camouflage clothes and documents were seized in the raids.
Turkey launched Operation Euphrates Shield into Syria on August 24 in support of Free Syrian Army (FSA) to try to push Daesh away from its border area, and has also frequently carried out raids on suspected Daesh safe-houses in Istanbul and other cities.
