ANKARA, April 1 (Xinhua) — Turkish police on Friday detained 15 suspected members of the Islamic State (IS) in tourist city of Izmir in western Turkey, private Dogan news agency reported.

Turkish Izmir police directorate sent several police teams early Friday morning to catch the IS suspects in various streets in several districts in the Izmir city and arrested the 15 IS suspects, according to the report.

The detained 15 IS suspects reportedly staged the armed attacks in the provinces of Adana and Mersin in southern Turkey in 2015, said the report.

The arrests came at a time when the Turkish troops are on high alert to catch IS militants who have been detected inside the country and are allegedly in pursuit of carrying out bomb attacks in crowded places across the country.
