Syria's 600,000 refugees face severe winter conditions across the country and the surrounding region.
This adds more misery to the increasing food shortage caused by heavy rain followed by a drop in temperatures.
Stormy weather sparked widespread flooding, prompting chaos on the roads and a nationwide school closure. The number of Syrian refugees in Lebanon is already totaling 156,000, according to UN figures, and 200,000 according to the Lebanese government.
UNHCR spokesman Adrian Edwards, spokesman for the UN High Commission on Refugees, said: "Even with the winter preparation work that has been done in recent months, many refugees in both camp and non-camp situations are facing particularly cold and damp conditions. At the same time, there has been no let-up in the numbers of people fleeing Syria."
