ANKARA, Turkey – Turkey's state-run news agency says police in Istanbul have detained some 40 foreign nationals suspected of having links to the Islamic State group.
Anadolu Agency said police launched simultaneous raids on 23 addresses in the city's Fatih neighborhood late on Sunday. It said those detained included nationals from Azerbaijan, Iran, Iraq and Afghanistan.
Anadolu said some of the suspects had traveled to conflict zones in Syria several times.
Turkey has suffered a wave of suicide bomb attacks blamed on the IS group since last year that have killed more than 200 people.
Turkey last month sent tanks and troops into northern Syria to clear a border area of IS militants.
