Q: (CNN) European Union and Turkish officials reached an agreement Friday on how to deal with a flood of Syrian refugees. "(The) agreement isn't a silver bullet, but part of EU's comprehensive strategy on migration," European Council President Donald Tusk tweeted Friday. The deal came after talks involving Turkish Prime Minister Ahmet Davutoglu, Tusk and a handful of other key European officials. The final language was then put up for a vote before representatives from the 28 European Union member states, who approved it unanimously, according to the European Council president. The talks were held to address the largest influx of refugees into Europe since World War II, though the more than 1 million people who have fled to there pale compared to the more than 2.7 million registered in Turkey alone. The discussions could be significant for Turkey not only in receiving financial aid to deal with this problem, but also expedite its push to join the 28-member European Union.EU states unanimously approve the agreement with Turkey, a top leader tweetsEuropean Council President Donald Tusk says the deal "isn't a silver bullet," but is key to Europe's migrant planThe agreement also addresses Turkey's desire to join the European Union
