The worsening Syrian crisis has prompted the United Nations to make its biggest ever appeal for humanitarian aid.
The UN said it needs $5 billion to help the "staggering escalation of the refugee crisis."
Andrew Harper from the UN Refugee Agency said: "The numbers are just massive and there's no end in sight, no light at the end of the tunnel. We have politicians talking and talking and talking but there's nothing on the humanitarian front having any impact."
This week, we have been hearing stories of life inside the Zaatari refugee camp in Jordan.
ITV News Middle East Correspondent John Ray:
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.
