Hundreds of Syrian refugees flocked into Turkey on Monday.
Some 130,000 Syrian Kurds have fled to Turkey since Friday to escape the advance of ISIL militants.
The country is facing one of the biggest influxes of refugees since the start of the Syrian civil war, more than three years ago.
Deputy Prime Minister Numan Kurtulmus insists Turkey is ready to react.
“I hope that we are not faced with a more-populous refugee wave. But if we are, we have taken precautions. We have planned ways of sending those people to safer and further away places, if necessary,” he advised.
Many of those who escaped said militants from the al-Qaeda breakaway group were executing people in the Syrian villages they seized, in order to frighten locals into obedience.
Ismail Ahmad, a Syrian refugee on the border with Turkey, described the situation in his hometown.
“They came into our houses and dragged our daughters away. What kind of Muslims are they? What kind of Islam is this? They are beheading people. We came here to seek shelter,” he said.
Another refugee added:
“We’ve been waiting at the border for the past four days with our children. We’re in a miserable situation.”
Turkey is currently hosting 1.3 million displaced Syrians. Officials estimate the relief effort has cost the government in excess of 2.3 billion euros.
