Tens of thousands of Syrian refugees are moving to Turkey's border to flee heavy fighting near the city of Aleppo, officials and activists have said, according to BBC News.
Turkish Prime Minister Ahmet Davutoglu said up to 70,000 may be heading to the border, while a monitoring group put the number at about 40,000.
Intense Russian air strikes have helped Syria's government troops make advances near the country's largest city. Meanwhile, Russia accused Turkey of preparing an invasion into Syria.
Speaking at the donor conference in London, Davutoglu said: "Now 10,000 new refugees are waiting in front of the door of Kilis (Turkey's border town) because of air bombardment and attacks against Aleppo."
He added that 60,000-70,000 people "in the camps in north Aleppo are moving towards Turkey". The Observatory put the number at about 40,000.
