(IRIN) – Not so long ago, Syria had an education system that was the envy of the Arab world and was reflected in its 90 percent literacy rate. But education has become yet another casualty of a civil war now in its fifth year. Nearly half of the four million Syrians who have fled their country are living in neighbouring Turkey where authorities initially welcomed hundreds of thousands of the refugees in camps near the Syrian border. Many have since become tired of camp life and moved to cities in search of a more dignified existence.
