UN teams in Lebanon help refugees fleeing Syria As violence rages in Syria, nearly 28,000 refugees have fled into Lebanon. Seeking safety and shelter, most arrive on foot and at night. Many leave with few belongings and little cash. With only the clothes they were wearing, Rima and her five children fled to Lebanon from Homs when rockets destroyed her home. We heard gun shots and bombs so we started running as fast as we could. I was afraid for the children," she said. The number of refugees fleeing Syria has doubled since March, according to the UN, with the biggest flows heading into Turkey, Lebanon and Jordan. The highest number of people - more than 33,000 - have crossed the Turkish border. In Lebanon, vouchers are given to refugee families by the United Nations World Food Programme. They can be used to buy fresh produce in local shops. "The World Food Programme is using vouchers here in Lebanon to assist the Syrian refugees," said WFP spokeswoman Laure Chadroui. This is also an innovative system that helps the local economy and alleviates the burden on the host communities. The UN refugee agency has doubled its forecast for the number of people who will have fled Syria by the end of the year to 185,000. More about: Humanitarian crisis, Lebanon, Refugees, Syria
