The head of the White Helmets, a civilian aid organisation working in rebel-held areas of northwest Syria, is accusing the United Nations of being too poor in its response to the earthquake.

Raed al-Saleh says the UN is not acting impartially. The first UN aid convoy crossed the border from Turkey and entered the region on Thursday. But the White Helmets say the logistics were planned to be sent there before the earthquake and did not contain essential logistics for the rescue operation.

While speaking to the UN delegation in Geneva via video link from Idlib, Mr. Al-Saleh said the relief fleet that arrived in northwestern Syria 100 hours after the earthquake had only six truckloads of aid. And they were supposed to be there before the earthquake.

Land border crossings from Turkey to Syria have been reduced at Russian insistence. As a result, the distribution of UN humanitarian aid to parts of Syrian territory under the control of the opposition has been interrupted for more than a year.

Russia says aid supplies should go through the government in Damascus. But the White Helmets today claimed on Friday that the Syrian government had sent 'nothing' into northern Syria after the earthquake.

Mr. Al-Saleh suggested the United Nations open some more humanitarian corridors, but they "didn't want to anger Russia," he said. UN officials must be Mr. Do not accept this interpretation of al-Saleh.

Martin Griffiths, the head of the UN's emergency relief agency, is traveling to northwest Syria this weekend. However, it is not yet clear whether he will meet White Helmets personnel during the visit.

Four days have passed since the earthquake struck and the situation in north-west Syria has become desperate due to lack of aid.

The UN's World Food Program (WFP) said on Friday that food stocks are running out fast in northwestern Syria, where 90% of the population is dependent on aid, -Reuters reports.
