At a summit in Brussels on Monday, Turkish and EU leaders tentatively reached a deal to swap migrants in which Turkey would take back asylum seekers from Greece and Syrians living in Turkey would be resettled in Europe. The deal is supposed to put an end to the mass migration through Greece and the Balkans. Turkey is now demanding 6 billion euros in aid from the EU and expedited EU membership talks and visa-free travel for Turkish citizens. Brussels previously agreed to give Ankara 3 billion euros in aid. Turkey has done little thus far to stem the flow of migrants despite repeated promises to do so.
