On Tuesday 29 November, Stephen O'Brien, the United Nations under-secretary-general for humanitarian affairs and emergency relief coordinator, told the European Parliament that the humanitarian aid brought to Syria was no longer enough given the scale of the disaster.
"Aleppo has become the climax of the horror. The conflict absolutely must be resolved", he said in the presence of Staffan de Mistura, the UN special envoy in charge of peaceful resolution of the ongoing conflict in Syria.
