Turkish security forces captured seven suspects over links to Daesh terrorist organization in anti-terror operations in capital Ankara, Turkish authorities said Friday.

Ankara Security Directorate's Counter-terrorism and Intelligence Units conducted the simultaneous operations and detained the suspects, including two Iraqi nationals.

The suspects, who had crossed into the country after operating in neighboring Syria and Iraq, are accused of membership in a terrorist organization and having contacts with other Daesh members.

Amid fears that Daesh terrorists who fled Syria could travel to Europe and Turkey, authorities have heightened crackdowns on the terrorist group with almost daily operations to capture suspects.

The country is at the forefront of efforts to quell threats from the terrorist group, which partly depends on foreign recruits for fighters.

Some 4,043 terrorists, including 1,858 foreigners, were detained by Turkish forces, 61,158 people from 148 countries were barred from entering Turkey, and 6,151 were caught and extradited between 2011 and 2018.
