Turkish authorities have arrested three suspected members of the "Islamic State" (ISIS) terrorist group in Istanbul, including two Pakistanis and a Briton, state media said Tuesday, according to AFP.

The state-run Anatolia news agency said the Pakistani suspects had been detained last week in a raid on their homes in Istanbul's central Mecidiyekoy district. Police then expanded the operation based on intelligence the suspects provided and detained the British suspect, identified as Hasan H., at a bus stop in the conservative Fatih district, it added.

All have now been remanded in custody by a court.
