The statistics on Syria’s civil war are horrifying. Since March 2011 around 200,000 people have been killed and 6.5m people have become internally displaced. A new report from the UN High Commissioner for Refugees, published on January 7th, brought another grim figure: Syria has overtaken Afghanistan to become the biggest source of refugees in the world. More than 3m Syrians, or one in eight of its population, had fled the country by the end of June 2014, the most recent date for cross-country comparisons. In the six months since, another 300,000 have left.
