Anti-terrorist police in Turkey have arrested 38 foreigners in southern Turkey who were on their way to join ISIS, AFP has reported, quoting a report that appeared in the Anatolia news agency.

The foreigners, said to include 10 women and 15 minors, comprised of nationals from Indonesia, Iran, Iraq and several other Asian countries. Also arrested were two Turks who were accused of offering logistical help to the foreigners.

The arrests were made in the province of Adana, although it's unclear when the suspects were apprehended.

Facing pressure from NATO to do more to stop the flow of fighters into Syria, and in the wake of the upcoming G20 Summit to be held in Turkey on Nov. 15-16, Ankara has embarked on a crackdown on ISIS, according to Today's Zaman.

Twenty suspected ISIS members or sympathizers were arrested on Nov 6. in Antalya, the city that will host the G20 Summit. Another 41 were also arrested on the same day at Turkey's Ataturk Airport, on their way to join ISIS after a Moroccan passenger tipped off the authorities.

The G20 Summit is expected to bring together world leaders including U.S. President Barack Obama and his Russian and Chinese counterparts.

Earlier on Monday night, while speaking to CNN, Turkish Prime Minister Ahmet Davutoglu reiterated Ankara's position that any solution in Syria must include the departure of President Bashar al Assad.

"The question is not how and how long Assad will stay, the question is when and how Assad will go," said Davutoglu.

He also warned European leaders that unless Assad relinquished power, Syrian refugees in Europe would never return home.

"What is a solution? A solution is very clear. When, one day ... millions of Syrian refugees decide to go back to Syria, assuming that there is a peace in Syria, then this is a solution. If Assad stays in power in Damascus, I don't think any refugee will go back," warned Davutoglu.
