Turkey's foreign minister says his country might need United Nations help if more Syrian refugees arrive in Turkey.
Ahmet Davutoglu says he spoke to UN Secretary-General Ban Ki-moon early Friday to inform him after 2,500 refugees crossed into Turkey on Thursday.
Davutoglu says nearly 24,000 Syrian refugees have crossed into Turkey since the crisis began.
He also said that the attacks by the Syrian military are "seriously worrying us."
