ANKARA: Turkish President Recep Tayyip Erdogan on Friday told the European Union to stick to past deals on migrants and refugees and aid neighbouring countries as fears of a new exodus from Afghanistan mount.

Rising numbers of Afghan migrants could present "a serious challenge for everyone", Erdogan said in a phone conversation with Kyriakos Mitsotakis, prime minister of neighbouring Greece.

Athens has already said it may send Afghans arriving on its shores back to Turkey, which it regards as a "safe" country for migrants.

Ankara has repeatedly accused EU capitals of failing to hold up their end of the bargain.
