At In Focus, a photo gallery on the six million displaced by the war in Syria:
While the West debates airstrikes on Damascus and the Syrian government battles a wide array of rebel forces, the Syrian people are enduring what the World Health Organization now calls the worst ongoing humanitarian crisis on earth. Four million Syrians are internally displaced; with homes either destroyed or unsafe, they have moved to temporary housing within Syria's borders. Another two million have now fled the country, pouring into neighboring countries at a rate of nearly 6,000 every day. Lebanon, Jordan, Turkey, Iraq, and Egypt are taking in the vast majority of these refugees, working with the United Nations, Red Crescent, and many other charitable groups to provide shelter, security, food, and water. The resources are being stretched thin, after years of a growing crisis, and the approach of winter and threat of escalating violence have many aid organizations fearful about what's to come.
Here's an aerial view of the Zaatari camp in Jordan, about 12 km from the Syrian border, which holds roughly 115,000 refugees:
John Kerry visited the camp recently, and "spent about 40 minutes with half a dozen refugees who vented their frustration at the international community's failure to end Syria's more than two-year-old civil war".
