Turkey says the United Nations may need to create a safe zone within Syria to accommodate a growing number of refugees from the fighting there.
Foreign Minister Ahmet Davutoglu says Turkey is already hosting nearly 70,000 Syrians fleeing the revolt against President Bashar al-Assad and may soon be unable to cope.
He told the Hurriyet newspaper on Monday that Turkey would "have to welcome them in Syrian territory" under UN auspices.
Turkey has opened a centre in Gaziantep to receive international aid and began distributing aid to refugees in Syria at the weekend.
Relations betwen Turkey and Syria have deteriorated sharply since the uprising began.
