A British doctor has gained a first-hand insight into the grave humanitarian situation in Syria after using his annual leave to volunteer in the country.
Omar Gabbar is a consultant at Leicester General Hospital and he spoke to ITV News:
Mr Gabbar has been working with the charity Hand In Hand For Syria.
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.
