In its statement on the call, the USA said Tillerson discussed a previous meeting with Canadian Foreign Minister Chrystia Freeland in which he called "out North Korea's unlawful and risky development of nuclear and ballistic missile programs and stressed the urgent need for all parties to implement UNSCRs related to North Korea", a reference to UN Security Council Resolutions.
France, which is a permanent UN Security Council member, hosted a foreign ministerial meeting on the issue in Paris on Tuesday.
In September 2014 the Organization for the Prohibition of Chemical Weapons (OPCW) says chlorine was used as a weapon "systematically and repeatedly" on villages in the central province of Hama and northwestern Idlib province.
"So, by and large, we categorically disagree with the approach employed by the Americans who have actually swept the real probe into previous cases of chemical weapons use under the rug", Peskov noted. "We've been firm in our determination to hold parties accountable for the use of chemical weapons, which have killed far too many Syrians".
The comments came a day after an "apparent chlorine gas attack" in east Ghouta, an enclave of rebel support in the Damascus suburbs, which left at least 20 civilians - majority children - struggling to breathe. The Syrian government denies using chemical weapons; Russian Federation says extremists have used chemical weapons in the past.
US blames Russian Federation for latest chemical incident in Syria, regardless of who carried it out US Secretary of State Rex Tillerson pointed the finger at Syrian President Bashar Assad for the reported chemical incident in East Ghouta, while ultimately blaming Russian Federation for it, regardless of who actually committed the attack.
The following month the United States and regime-backer Russian Federation reach a deal to eliminate Syria's chemical weapons by 2014, averting punitive U.S. strikes.
The Guardian reports that between 2012 and 2017, there were more than 130 reported chemical attacks in Syria, "with the majority attributed to the Assad regime".
"The current situation can not continue", French Foreign Minister Jean-Yves Le Drian said.
Hours before the conference, France said it froze the assets of 25 Syrian companies and executives, alongside French, Chinese and Lebanese enterprises that allegedly provided assistance to the Syrian government for the use of chemical weapons. The UK-based Syrian Observatory for Human Rights said at least 13 people had suffered suffocation in the incident.
"We call on the community of responsible and civilized nations to put the use of chemical weapons to an end". The United States also holds veto power at the Security Council. According to medical data, six people have sought medical attention because of breathing problems caused by a possible chemical attack.
