The Latest: Greece returns more Syrian refugees to Turkey

A public order ministry statement says the 17 men, four women and six children were flown Thursday from the eastern Aegean Sea island of Lesbos to Adana.

Under a deal struck last March between the European Union and Turkey, migrants reaching the Greek islands from Turkey are returned unless they can prove they merit asylum in Greece.

Island mayor Spyridon Galinos has pledged to help compensate them with prize money from Sweden's Olof Palme Memorial Fund that recognized the humanitarian acts of Lesbos residents.

Migrants staying at a crumbling warehouse in central Belgrade say they have trouble breathing because of the smoke from fires they have lit to warm up in freezing temperatures.

Andrea Contenta, the humanitarian affairs officer for Doctors Without Borders, says Europe should recognize that the flow of migrants has continued despite the closure of borders in the Balkans last year.

The leader of the European Union's presidency says that record numbers of migrants will try to cross the Mediterranean this spring and he wants the EU to work with Libya now to stem the flow.
