The disruption comes as humanitarian needs are at an all-time high after more than 12 years of war and after the devastating twin earthquakes that struck the region in February.
The UN and partners are hoping for a 12-month extension of the mandate to bring aid through the Bab al-Hawa crossing point – a lifeline for four million people in northwest Syria, the last bastion of the opposition.
The first draft resolution, presented by Brazil and Switzerland, called for a nine-month extension. Speaking before the vote, Brazil’s Ambassador Sérgio França Danese said that they “are working tirelessly to try to reach a text that is as consensual as possible.”
Although 13 of the 15 countries voted in favor of the resolution, it was rejected without a vote from Russia, one of the five permanent members of the Council. China, another permanent member, abstained.
A second resolution for a six-month extension was submitted by Russia, supported by China. Three countries voted against and 10 abstained.
