Today, some 70,000 Syrian refugees live at Za'atari refugee camp in northern Jordan. Thousands more people - many of them children - arrive every week, according to the United Nations Children's Fund (UNICEF).
The video below follows UNICEF's camp manager Konady Kone around the camp as he talks to refugees to assess their needs and addresses day-to-day problems such as the lack of hot water in the camp's toilets and hard living conditions caused by bad weather.
"At night it's very very cold," a Syrian man tells Kone. "In the daytime is manageable but at night is very cold."
Every refugee receives two blankets each, but the man tells Kone they are not enough to fight off the cold.
