Sunday’s raids were the latest salvo in a long-running conflict between Turkey and the Islamic State. Turkey has suffered numerous attacks linked to the Islamic State since 2014, most recently in the early hours of this year, when a fighter killed 39 people at a nightclub in Istanbul. This weekend’s raids occurred across a wide area seized in 18 provinces, including Ankara, Istanbul, Kocaeli, Bursa, Izmir, Konya, Bingol, Adana, Sanliurfa, Gaziantep, Adiyaman, Malatya, Kilis, Hatay, Corum, Antalya, Diyarbakir and Van.Until now, the Turkish police usually detained only small numbers of jihadists at a time. Detentions may not necessarily lead to court cases. Some Turkish government critics including Ahmet Yayla, a former counterterrorism chief in Turkey who is living now in the U.S. said officers may not be able to properly handle the paperwork, interrogations and bureaucracy associated with processing so many persons.
