"Syria condemns all the lies and allegations by the American and French foreign ministers about chemical weapons use in Syria," a foreign ministry official told state news agency SANA.
Twenty-one people were treated for respiratory problems after rockets were fired on the rebel bastion of Eastern Ghouta outside Damascus on Monday, which residents and medical sources said contained chlorine.
In response, 24 governments approved a new "partnership against impunity" for the use of toxic weapons at a meeting in Paris yesterday.
"Whoever conducted the attacks, Russia ultimately bears responsibility for the victims in East Ghouta and countless other Syrians targeted with chemical weapons, since Russia became involved in Syria," Tillerson told reporters.
French Foreign Minister Jean-Yves Le Drian, who chaired the meeting, said perpetrators "will not go unpunished."
And France announced sanctions against 25 people and companies it said were linked to Syria's alleged chemical weapons.
Damascus has been repeatedly accused of using chemical weapons, with the United Nations among those blaming government forces for an April 2017 sarin gas attack on the rebel-held town of Khan Sheikhun that left scores dead.
