Thirteen suspects linked to the terrorist group Daesh were detained yesterday in the southern city of Adana by gendarmerie forces.

Troops raided three buildings in the city's Saimbeyli district and rounded up the suspects while confiscating digital propaganda materials, Daesh banners and two shotguns in possession of the suspects.

Adana is home to İncirlik, a military base used by U.S.-led coalition forces' operations against Daesh in Iraq and Syria. Security forces have captured terrorist group's Adana "emir" earlier this year in the counterterrorism operations.Embattled by counterterrorism operations in Syria and Iraq, Daesh sees its numbers further dwindling with heightened crackdowns in Turkey. In the first six months of this year, security forces detained more than 5,400 suspects and arrested more than 900 in operations, while another 146 Daesh militants were "neutralized" in the same period in 838 operations across the country.

Since November 2017, Turkey has also stopped at least 5,000 foreigners seeking to join Daesh by crossing into Syria and Iraq through Turkey and sent them back to their countries of origin. Security forces have also foiled 10 attack plots. Figures show some 18,500 suspects were monitored for links to the terrorist group at airports upon their arrival.

The terrorist group started targeting Turkey in 2013 and targeted rallies, a main airport in Istanbul, a popular nightclub and other venues where terrorists killed scores of people.
