The UN has launched its biggest ever aid appeal for Syria as the scale of the refugee crisis continues to escalate. Aid agencies need over $5bn to fund their operations in and around Syria until the end of the year, the UN said.
The UN High Commissioner for Refugees, António Guterres, has described the conflict in Syria as "probably the most challenging humanitarian operation in decades".
Speaking at the launch of the UN's largest-ever aid appeal, he said he was concerned that the scale of the need in Syria was too large to be covered by the "traditional aid budgets of donor governments" alone.
Half the population at the Zaatari refugee camp are children. After escaping violence at home they are now growing up on the edge of war.
In my second special report, I see how charities in Zaatari are working with Syrian children to try to numb the painful trauma of war.
Zataari, a Syrian camp for more than 100,000 refugees, is a place so desolate that only the truly desperate would call it home.
