(MENAFN- Kuwait News Agency (KUNA)) Syrian refugees, fleeing the fighting battles between the Kurdish forces and the Islamic State in Iraq and the Levant (ISIL) in northern Syrian city of Tal Abyadh, continued their influx into Turkey Sunday.

Turkish News Agency (Ihlas) reported that many Syrian refugees huddled into Turkey today after the Turkish authorities decision to re-open the borders after several days of closure.

It added that over 15,000 Syrians have crossed the borders to seek refuge in Turkey due to the intensity of the fighting between ISIL and Kurdish forces in their city and the US-led coalition airstrikes.

Ihlas unveiled that the Kurdish fighters and Syrian opposition groups have managed to wrestle control over several areas in the countryside of Tal Abyadh, northwestern of the ISIL bastion of Al-Raqqah.

Under an "open-door" policy, Turkey has received over 1.8 million Syrian refugees since the start of the Syrian conflict in 2011.

But it has, in recent months, grown frustrated with the situation, claiming that it has been left to shoulder the burden of refugees while the West stands by.

Earlier, Turkish President Recep Tayyip Erdogan expressed concerns over the advance of Kurdish forces into Tal Abyadh, saying they could in the future threaten Turkey.

He said the places refugees had vacated were being occupied by the Syrian Kurdish group the Democratic Union Party (PYD) and the outlawed Kurdistan Workers Party (PKK).
