Turkish anti-terrorist police have detained 38 foreigners including women and children who were reportedly seeking to join the ISIS group in Syria, media reports said Monday.
Turkey has gone on the offensive against ISIS suspects ahead of the G20 summit in the Mediterranean resort of Antalya and after a spate of bloody attacks blamed on the jihadists.
World leaders including US President Barack Obama, Vladimir Putin of Russia and China's Xi Jinping will be attending the G20 gathering on November 15-16, with the focus likely to be on the Syrian conflict, the war against IS and the refugee crisis.
The suspects held in the southern province of Adana included nationals from Iraq, Iran, Indonesia and several central Asian nations, the Anatolia news agency said, without specifying when they were detained.
Among them were 15 children and 10 women. Two Turks were also held for helping the group.
Anti-terrorism police have rounded up dozens of ISIS suspects in recent weeks including 20 held in the G20 host city of Antalya last Friday.
Another seven foreigners were detained in Adana on Saturday on suspicion of planning to join ISIS, while the army said 12 suspects were detained in Karkamis on the Syrian border on Sunday.
Turkey has been hit by several attacks blamed on the extremists including twin suicide bombings in Ankara last month that killed 102 people.
Under pressure from its NATO allies, Ankara has stepped up security on the long and porous border with Syria and has expelled more than 2,300 suspected jihadists since 2014, according to official figures.
