Anadolu Agency reported today that Istanbul police conducted simultaneous operations in multiple districts to detain 82 foreigners. The suspects had allegedly been active in conflict zones with IS and planned on going to Syria.
Separately, Anadolu said 11 Syrian nationals were detained in the southern province of Adana for alleged links to IS.
The operations are part of Turkey's ramped up effort to clamp down on IS. Police detained more than 170 IS suspects in a sweep in the capital, Ankara, yesterday.
