Turkish Foreign Minister Mevlut Cavusoglu said on Wednesday that they are in negotiations with Russia and other members of the United Nations Security Council on the extension of a cross-border aid operation into war-torn Syria, less than 10 days before the mandate expires.

Officials have warned of a humanitarian catastrophe if the mandate is not renewed, as millions of people depend on the humanitarian aid currently funneled from a single border crossing in Turkey into northwest Syria, an arrangement authorized by the UN Security Council.

Speaking alongside Russian Foreign Minister Sergei Lavrov in the Turkish resort of Antalya, Cavusoglu said the mandate, which expires July 10, should be extended. Ankara would continue to work with Moscow on a political solution to Syria’s crisis and the maintenance of an existing ceasefire in the north, he added.
