Turkish police arrested three other suspected terrorists in Istanbul -- a Turk, an Iraqi and a Syrian -- the state-run Anatolia press agency reported.
Turkish security forces on Tuesday arrested 10 suspected ISIS members at the Syrian border, one of whom was wearing an explosives vest, three days after a suicide attack in Istanbul, officials said.
The local governor's office said two of the foreign nationals arrested in the southern Gaziantep province were injured in an exchange of gunfire with Turkish troops. Three others managed to flee the scene.
One of those captured was wearing an explosives belt which was ready to be detonated, the governor's office said.
The Dogan news agency published pictures of the suspects on their knees with their hands behind their heads, along with what appeared to be an explosives belt.
Turkish police arrested three other suspected terrorists in Istanbul -- a Turk, an Iraqi and a Syrian -- the state-run Anatolia press agency reported.
The arrests come as the police hunt three Turkish suspected members of an ISIS cell believed to be planning further attacks in public places after Saturday's attack in Istanbul, which left four foreigners dead.
Three Israelis and an Iranian were killed and 39 people injured when a man identified by authorities as Mehmet Ozturk from Gaziantep blew himself up on Istiklal Caddesi, a famous shopping street in the heart of Turkey's biggest city.
No group has claimed responsibility for the attack but Turkey's government said Ozturk had links to ISIS terrorists.
ISIS has been blamed for four of six bombings that have rocked Turkey in the past eight months, including a massacre at a peace rally in the capital Ankara in October that claimed 103 lives.
A radical offshoot of the rebel Kurdistan Workers Party (PKK), with which the state is at war in southeast Turkey, claimed the other two attacks.
