Increased aerial bombardment in Syria has urged tens of thousands of Syrians to move towards the Turkish border from the Syrian city of Aleppo, Turkish Prime Minister Ahmet Davutoglu said on Thursday at a fundraising conference in London.

Davutoglu cited new information he had received on his way to London, saying that “ten thousand new refugees are waiting in front of the door of Kilis because of air bombardments and attacks against Aleppo.”

Kilis is a border province situated in southern Turkey adjacent to an area of Syria largely opposition-held.

The Prime Minister expressed his concern regarding the settlement of the recent pour of refugees. “Sixty to seventy thousand people in the camps in north Aleppo are moving towards Turkey. My mind is not now in London, but in our border – how to relocate these new people coming from Syria?” he added. “Three hundred thousand people living in Aleppo are ready to move towards Turkey.”
