Turkish police have detained a Belgian man of Moroccan origin on suspicion that he scouted out the target sites for Islamic State of Iraq and the Levant (ISIL) in attacks that killed 129 people in Paris a week ago, security sources said on Saturday.
Ahmet Dahmani, 26, was detained at a luxury hotel in the southern coastal city of Antalya, the source said.
Two other men, both Syrian citizens, were also detained on a nearby highway on suspicion that they had been sent by ISIL in Syria to ensure Dahmani's safe passage across the border and were planning to meet him.
Counter-terrorism police first became aware of Dahmani when he arrived on a flight to Antalya and tracked him to the hotel in the Manavgat district of the city.
Turkey has recently conducted many anti-terror operations against ISIL.
The country deported a group of Moroccans detained at Istanbul's main airport this week over suspected links to ISIL.
The eight, who said they had arrived at Ataturk airport on Tuesday night from Casablanca for a holiday, were detained by border police and questioned by profiling experts who flagged them as suspected militants, a government official said.
