Turkey has detained 357 suspected Islamic State (IS) members nationwide following an eight-hour siege in Yalova where police clashed with militants. The operation, which included raids on 114 addresses in Istanbul and other provinces, comes amid a broader crackdown on IS suspects. This surge in operations follows recent IS-linked incidents globally, including U.S. strikes in Syria and alleged inspiration for attacks in Nigeria and Australia. Turkey has a history of IS attacks, particularly between 2015-2017.
