The United Nations Security Council will discuss delivery of weapons from Turkey to Syria on Tuesday at Russia’s request, Uruguay’s Permanent Representative to UN Elbio Rosselli, who is presiding over the UN Security Council in January, told journalists on Monday. He added that the meeting would take place behind the closed doors.

“Yes. The question of delivery of (weapons) across the Turkish-Syrian border will be raised tomorrow (Tuesday) as part of the general discussion. The consultations will take place at Russia’s request,” the diplomat told TASS.

According to Rosselli, Jeffrey Feltman, the United Nations Under-Secretary-General for Political Affairs, is to deliver a report.

In December 2015, Vladimir Safronkov, Russia’s Deputy Permanent Representative to the United Nations, said that Moscow was extremely concerned with the ongoing arms supplies to Syria and the penetration of terrorists into the country via the U.N.-monitored checkpoints at which U.N. observers are supposed to check the relief cargoes.

Safronkov said that Russia had suggested applying the U.N. monitoring mechanisms to all the cargoes bound for Syria, including those declared as relief cargoes. However, the United Nations Security Council ignored the Russian initiative as it was preparing Resolution 2258, which authorizes the delivery of relief cargoes to the conflict-stricken areas in Syria directly from the territories of neighbouring countries until January 10, 2017.
