UN: Increasing Refugee Population Faces Strained Aid Community Heather Murdock GENEVA, BEKAA VALLEY AND BEIRUT, LEBANON - In his early 20s, Mohammad was a law student who raised bees on his uncle's farm in Syria. But in 2013, he faced a terrible choice: Join the military, join a rival militant group, face prison or flee his country. "What if I had to kill my own people?" he said at a mobile phone shop in an urban refugee camp in Beirut. "I tried to flee to Europe many times. I was caught by the Egyptian secret police, and they sent me to Damascus." There are now 70 million people "forcibly displaced" in the world, and their numbers are growing rapidly, according to the United Nations. Humanitarian aid is increasingly scarce, and the increase in refugees "is outpacing the rate at which solutions are being found," according to U.N. Secretary-General António Guterres. As more people flee their homes, it is becoming increasingly difficult to determine who is entitled to protection under international law, and who is not. "We need to uphold the refugee definition that is enshrined in the international legal system because it is strong, and we can leverage it in our discussions with States," U.N. High Commissioner for Refugees Filippo Grandi said at a Geneva conference on Tuesday. "We are not always successful, but we can use it. But we have to recognize also that many other people on the move have vulnerabilities and therefore need help." .
