The UN chief has welcomed a decision on Friday by the Security Council to extend the UN cross-border aid operation in northwest Syria for another 12 months, providing a lifeline for more than 3.4 million people in need, including some one million children.

Progress towards resolving Syria’s decade-long war is unlikely, given the ‘gulf of mistrust’ among parties and complexity of conditions on the ground, the chief UN mediator for the country told the Security Council on Friday, as he urged delegates to unite around elements of resolution 2254 (2015) and called for a new international dialogue to achieve a breakthrough.

The imminent closure of the last cross-border aid lifeline to northwest Syria must be postponed beyond the 10 July deadline, UN humanitarians said on Friday, noting that no cross-line supplies had reached Idlib from Damascus, in 11 months.
