The United Nations has said that if the conflict in Syria continues at its current pace the number of people requiring humanitarian assistance within the country would rise by 1.5 million by early next year.
In an interview ahead of Friday's fifth Syrian Humanitarian Forum in Geneva, John Ging, operations director for the UN humanitarian office, has said the number of the Syrians that would need some form of humanitarian aid could increase from 2.5 million to four million by early 2013.
"People need to be aware of just how desperate the situation is inside Syria for the people there, how unbearable it is, and how they are suffering and falling into ever deeper despair and humanitarian need ... It's just getting a lot worse very rapidly for the ordinary people", Ging said.
Ging also said UN projections saw the number of Syrian refugees in neighbouring countries reaching 700,000, up from the current estimated 400,000 in early 2013.
Of the 2.5 million Syrians currently in need of humanitarian aid in Syria, Ging said the United Nations and other organisations were only able to reach 1.5 million. Funding was cited as one reason for the shortfall.
Programmes for Syrian refugees in camps in neighbouring countries, including Turkey, Lebanon and Jordan, are also seriously underfunded, said Ging. Donors have so far provided only 50 per cent of the amount needed, he said.
The UN humanitarian projections come as Syrian opposition figures are meeting in the Qatari capital, Doha, to forge a broad-based leadership group sought by the international community.
