Turkish police detain 40 people suspected of IS links
Turkish police have detained some 40 foreign nationals suspected of having links to the Islamic State group (IS).
Officers launched simultaneous raids on 23 addresses in Istanbul's Fatih area late on Sunday, according to reports.
Those detained were said to include nationals from Azerbaijan, Iran, Iraq and Afghanistan.
The Anadolu agency said some of the suspects had travelled to conflict zones in Syria several times.
Turkey has suffered a wave of suicide bomb attacks blamed on the IS group since last year which have killed more than 200 people.
Last month, Turkey sent tanks and troops into northern Syria to clear a border area of IS militants.
