Hmaidi Abdullah, a Syrian political analyst, told Xinhua the US threats of military action on Syria were "serious", saying they reflect the USA desire to undermine the Russian-Iranian-Syrian alliance, which is gaining the upper hand in Syria.
"If you took the decision to carry out an illegal military adventure - and we do hope that you will come to your senses - well then you will have to bare responsibility for it", said Nebenzia.
President Donald Trump cancelled a planned trip this weekend to South America where he was to participate in a summit with other Western Hemisphere leaders, the White House said, as he contemplates a military response to a chemical weapons attack in Syria.
Intense political clashes were witnessed in the UN Security Council on Tuesday between Russian Federation and the USA over the recent allegations of chemical weapons used by the Syrian government forces in the battles against the rebels in Douma district of Damascus.
Prior to the vote, U.S. Ambassador to the U.N. Nikki Haley said, "At a certain point, you're either for an independent and impartial investigation, or you're not".
On Monday, Russia and the Assad regime both offered during the U.N. Security Council meeting to take OPCW investigators to Douma.

U.S. officials told Reuters that Washington was weighing a multinational military response.
White House officials refused to say whether the response included the possibility of prolonged US military action in Syria or would amount to more than just a "one-off" airstrike.

A day after its installations, many BSP leaders linked the saffron coat as the colour of Lord Buddha and garlanded the statue. Saffron is unusual as we have always seen his pictures and statues in dark coloured western outfits, blazer and pants .
On Tuesday, the Organisation for the Prohibition of Chemical Weapons said it would soon deploy a team to Douma after Damascus said it was "ready to provide all necessary assistance to the mission". The White House said he later spoke with British Prime Minister Theresa May and the two "agreed not to allow the use of chemical weapons to continue".
"Rather than go deep into Douma and get bloodied badly, a chemical weapons attack was used to sow terror among the population from which Jaish al-Islam draws support", Syria analyst Nick Heras said.
But Kremlin spokesperson Dmitry Peskov warned that "making any deductions is wrong and dangerous", suggesting that rebels could have staged the attack themselves to pin the blame on Damascus.
The President met with his top advisors Monday evening to weigh military options against Bashar al-Assad's brutal regime; saying the Syrian government will pay a "big price" for the illegal chemical attack that killed over 60 civilians.
Earlier Tuesday, Syria invited the OPCW to send a fact-finding mission to Douma, the last rebel stronghold in the eastern Ghouta suburbs.
Trump said the U.S.is still investigating the possible involvement of the Iranian and Russian governments.
Four U.S. officials told NBC News that the Russian military is jamming U.S. military drones flying over Syria in an effort to disrupt the U.S.' ability to retaliate against chemical weapons attacks in Ghouta. The latest veto prevented the adoption of US-drafted resolution to investigate chemical weapons use in Syria aimed at identifying the perpetrators. Ali Akbar Velayati, an aide to Iran's supreme leader, spoke upon arrival in the Syrian capital on Tuesday, and was quoted by Iran's state-run news agency IRNA.
The chemical attack raises a number of questions.
"Assad needs every operation to be low casualties, or his army will not have the numbers to move on any other rebel controlled areas", Heras said.
