Three Daesh suspects were captured in the Mediterranean Turkish province of Mersin yesterday. Authorities did not reveal their identities or nationalities but said suspects acted as "executioners" for the terrorist group and sneaked into Turkey from Iraq and Syria.

Amid fears that Daesh militants who fled Syria may likely hit Europe and Turkey, authorities heightened crackdowns against the terrorist group with almost daily operations to net suspected militants.

Though Daesh lost many strongholds in Iraq and Syria, a controversial deal between the militants and Syrian groups linked to the PKK, a major terrorist group which carries out attacks in Turkey, helped their safe evacuation in Syria.
