UN Secretary General Antonio Guterres told Al Arabiya on Friday that he was deeply concerned about developments in Syria, saying the region was now in a cold war and there were no channels for calm.
The Secretary General said that France had submitted a proposal to restrict the veto in resolutions on crimes against humanity.
"Syria indeed today represents the most serious threat to worldwide peace and security", Guterres said.
"The Cold War is back - with a vengeance but with a difference", Guterres told the Security Council during a meeting requested by Russian Federation.
During the meeting, Russian Federation accused the West of having the sole aim in Syria of overthrowing the regime as it asked US, French and British leaders to refrain from military action.
He referred to Washington's latest statements on Syria as well as to United States interventions in recent years in both Iraq and Libya. "Let us not forget that, ultimately, our efforts must be about ending the awful suffering of the Syrian people", he added.More news: Giroud Double Completes Comeback For Chelsea

Syria will assume the presidency of the 65-nation Conference on Disarmament, based in Geneva, on May 28 and hold it over four weeks, until June 24. "But should the United States and our allies decide to act in Syria, it will be in defense of a principle on which we all agree", Haley told the UN Security Council.
Mr Guterres deplored the use of chemical weapons, which he described as "abhorrent."Earlier on Friday, the Secretary-General had called on the Security Council to create an independent body to determine who had used chemical weapons in Syria".
During the meeting, Britain's permanent representative to the United Nations Karen Pierce said that Russian actions regarding Syria are "the latest in a pernicious chronology of disregard for global law" by Moscow.
On Wednesday, I called the ambassadors to the UN of the United States, Russia, the United Kingdom, China and France and I reiterated my deep concern about the risks of the current stalemate in that 15-member organization with respect to the Levantine country, the Portuguese diplomat indicated.
The Swedish-drafted text calls for the establishment of an investigative panel to identify the perpetrators of chemical weapons use in Syria after Russian Federation this week vetoed a USA proposal to set up such a mechanism.
