Jordan is already swelling with Syrian refugees and is now having to turn away some families who are desperate to escape the war.
ITV News has been reporting from the Zaatari refugee camp, a place now home to more than 100,000 people.
Every day, more and more refugees arrive on the border, hoping to reach the camp, but some say that they are being sent back over the border.
From Jordan, ITV News Middle East Correspondent John Ray reports.
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.
