Moscow has information that militants were ordered to launch an offensive in Syria after Washington's possible military action in the country, according to the envoy. He added that terrorists would benefit from feasible attack on Syrian government troops.
"We continue to observe dangerous preparations for an illegal military action against a sovereign state in breach of international law. Not only the use of force, but also a threat to use it violates the UN Charter," Nebenzya said at a meeting of the UN Security Council.
The Russian envoy has called on the US and its allies to reconsider their decisions on Syria, stressing that Moscow is ready to engage in cooperation.
According to the ambassador, the recent events in Iraq and Libya demonstrate that the US partners have a purely consumer-oriented attitude towards the Security Council.

"They need the Council as a cover for Iraqi test tubes," Nebenzya said, referring to the 2003 US-led Iraqi intervention prompted by the unfounded allegations that Baghdad was in posession of chemical weapons.
"You show us the same virtual empty test tube now. Irresponsible US behavior that violates international law and the sovereignty of states is unworthy of a permanent member of the UN Security Council," the envoy added.
Russia refuted the reports of the use of chemicals in the area of eastern Ghouta, where Douma is located, saying that its Center for Syrian Reconciliation found no traces of hazardous substances there. Moreover, Moscow said that it had warned earlier of the possibility of provocations involving the use of chemicals that would be aimed at blaming President Bashar Assad's government for attacks.
