Turkey promised to help stem the flow of migrants to Europe in return for cash, visas and renewed talks on joining the EU in a deal struck on Sunday that the Turkish prime minister called a "new beginning" for the uneasy neighbors.
Leaders of the European Union met Turkish Prime Minister Ahmet Davutoglu in Brussels on Sunday to finalize an agreement hammered out by diplomats over the past month, as Europeans struggle to limit the strain on their 28-nation bloc from taking in hundreds of thousands of Syrian refugees.
A key element is €3 billion ($3.2 billion) in EU aid for the 2.2 million Syrians now in Turkey. The money is intended to raise their living standards and so persuade more of them to stay put rather than attempt perilous crossings to the EU via the Greek islands.
