"We hope that there will be no point of no return, that the US and the allies will refrain from military action against a sovereign state," Nebenzia told reporters on Thursday, Xinhua news agency reported.
"We are very concerned about the situation, about the dangerous escalation."
The immediate priority of the Security Council is to avert the danger of war, said Nebenzia.
Asked whether there will be war between the US and Russia in case of a US military strike against Syria, Nebenzia said: "We cannot exclude any possibility, unfortunately, because we saw messages that are coming from Washington -- they were very bellicose. They know we are there (in Syria)."
"I wish there was dialogue through appropriate channels to avert any dangerous development."
He said any U.S. military action against Syria would be a violation of international law. Even the threat of use of force is against the UN Charter, he said.
