Police in the Turkish Mediterranean city of Antalya have detained three Russian nationals in a raid on suspected Islamic State (IS) militants, according to reports.
The Anadolu Agency said anti-terrorism police conducted the raids on Wednesday, a day after an IS suicide bomber detonated a bomb in Istanbul's historic Sultanahmet district, killing 10 foreigners, most of them German tourists.
Russia's consulate general in Ankara confirmed the detention of the trio.
"The reasons for their detention are being clarified," Consul general Alexander Tolstopyatenko said, according to the Tass news agency.
The suspects were allegedly in contact with IS fighters in conflict zones and had provided logistical support to the group, Anadolu reported.
The Russian Foreign Ministry in November said 2,719 Russians had left for Syria to fight for IS.
Of these, 160 have been killed, 73 have returned and been tried and 36 have been arrested, according to Oleg Syromolotov, the deputy minister of foreign affairs.
