The measure is facing a possible veto from Russia, Syria's ally, which wants to first see a report due on Thursday on a sarin gas attack in Khan Sheikhun before deciding on the fate of the inquiry.
The report findings were issued by the Organization for the Prohibition of Chemical Weapons and the UN's Joint Investigative Mechanism (JIM).
"Today's report confirms what we have long known to be true", said the U.S. ambassador to the UN, Nikki Haley.
The Spokesperson for the Operation Inherent Resolve Colonel Ryan Dillon told Sputnik on Friday that the US-led coalition forces have uncovered and destroyed chemical weapons that were in the hands of the Daesh terror group.
"The Security Council must send a clear message that the use of chemical weapons by anyone will not be tolerated, and must fully support the work of the impartial investigators", she said.
"This is not about politics or the contents of the next report, but about ensuring accountability for those who are using these bad weapons, whether they are United Nations member states or non-state actors", Haley wrote in a letter to fellow ambassadors last week.
The ministry's source added that Syria strongly condemns the direct and indirect accusations against it which were included in this report and the previous one since they represent a falsification of the truth and distortion of all accurate information about what happened in Khan Sheikhon.
After the attack, as images of dying children gasping for air circulated in the media, the US placed blame on the Syrian military while also accusing Russian Federation, which backs Assad's government, of pushing a "false narrative" that rebel forces were behind the incident. The Syrian government surrendered its chemical arsenal to the OPCW after the deaths of hundreds in a sarin attack on a rebel-held suburb of Damascus in 2013, although the opposition has long accused the regime of holding back some of its supply.
The JIM was unanimously created by the 15-member U.N. Security Council in 2015 and renewed in 2016 for another year.
The JIM has already found Syrian government forces were responsible for three chlorine gas attacks in 2014 and 2015.
