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. Gathered below are some images of these millions of refugees, who now find themselves trapped in desperate situations -- vulnerable, poor, homeless, jobless, and without much hope for their near future.
