UNITED NATIONS, December 18. /TASS/. The United Nations Security Council cannot work out a mechanism of cross-border aid deliveries in Syria and the number of border crossings, Russia’s Ambassador to the United Nations Vassily Nebenzia told reporters on Wednesday.

Nebenzia told reporters after the closed-door consultations on two resolutions on cross-border aid deliveries to Syria that Moscow insists the border crossings for aid deliveries be halved.

"We propose two checkpoints and six-month extension," he said.
