Syrian refugees react to riot police at the Istanbul-Edirne highway as refugees wait for permission to pass the Turkish-Greek border in Edirne, Turkey, 19 September 2015. Turkey has spent 7.6 billion US dollar on caring for 2.2 million Syrian refugees since the civil war began in 2011, Deputy Prime Minister Numan Kurtulmus said on 18 September. Turkey hosts more Syrians who fled their homeland than any other country. Most Syrians, however, have no legal right to work and rights groups report housing remains a huge issue for many.
