Turkish police detained at least 25 Daesh-linked terrorist suspects, including three senior figures in anti-terror operations conducted in two districts in Istanbul, reports said Tuesday.

Counter-terror squads from Istanbul Police carried out simultaneous operations targeting three houses and confiscated documents and digital material linked to Daesh.

Three of the suspects detained in the operations were Turkish, while others were foreign nationals, IHA reported.

The suspects are accused of ordering and planning attacks for Daesh terrorists.

They were taken to the police station for testimony.

Since Daesh has emerged as a terrorist group in war-torn Syria, Turkey has detained over 5,000 Daesh suspects and deported over 3,290 foreign terrorist fighters from 95 countries and refused more than 38,269 individuals' entry to Turkey.

According to Turkey's Justice Ministry, at least 780 people, including 350 foreigners, remain in detention — some of whom have been convicted — for suspected links to the Daesh terrorist group.
