Humanitarian agencies have pointed to the "total collapse of international solidarity" to address the Syrian refugee crisis, and called for more burden-sharing.

Lebanon, Turkey, Jordan and Iraq are unable to take any more refugees, the agencies pointed out, with Lebanon showing one refugee for every four residents. Lebanon has even claimed security reasons for limiting the influx.

Together, the four countries have taken in more than three million Syrians since 2011.

All these countries are now cutting back on Syrians they allow into their soil, said the International Rescue Committee and the Norwegian Refugee Council.

Only 18,453 Syrians have been able to find refuge abroad this October compared to the 150,000 last year.

The organisations called upon countries outside the region to provide financial support to Syria's neighbours and take in at least 5% of the total Syrian refugee population, reports Reuters.

14 million displaced
The UN refugee agency UNHCR has said that about 13.6 million people have been displaced by the conflicts in Syria and Iraq. Many face the oncoming winter without food and shelter.

Amin Awad, UNHCR's director for the Middle East and North Africa, decried the lack of international response to the crisis noting that the World Food Programme has cut rations for 4.25 million people due to lack of funds.
