The balance of the past five years is devastating: more than 250,000 people were killed. More than half of the population, a good 13.5 million people, are on the run, 8.7 million of them within Syria and 4.7 million in the neighbouring countries Turkey, Lebanon, Jordan, Iraq, Egypt and Libya. And more than 900,000 Syrians have, to date, filed an asylum request in Europe.
