U.S. has no evidence of Syrian use of sarin gas, Mattis says

The Syrian government rejected US allegations on Saturday that it had used chemical weapons to attack rebel-held Eastern Ghouta last month.

"The sarin gas attacks that they are claiming don't even occur".

"However, on February 2, US Secretary of Defense James Mattis says investigators are looking into reports that the Syrian government used sarin gas in recent chemical attacks, but there is no evidence of the gas usage so far". The ministry said in a statement on Saturday that the U.S. remarks about the use of chemical weapons in the Eastern Ghouta region of the east of the capital Damascus are "false claims", Xinhua news agency reported.

However, another official said that the Trump administration hopes that stepped-up global sanctions and diplomatic pressure against Damascus will help rein in Syria's chemical weapons program.

Mattis told reporters the Syrian government had committed multiple attacks using chlorine gas.

The Syrian Foreign Ministry has rejected the U.S. claims about the Syrian government using chemical weapons in the war as "lies".

Secretary of State Rex Tillerson said at the time the US had "very high confidence" that the chemical agent used in that deadly attack was sarin nerve gas.

The Syrian government denied the accusations, saying it's rebels who mounted the attack to frame the government and draw in a military action from the US.

He was of the opinion that if worldwide community does not act quickly to tighten the screws on Mr Assad, Syria's chemical weapons could spread beyond its borders and possibly even "to United States shores".

"You all have seen how we reacted to that, so the Syrian government would be ill-advised to go back to violating the chemical convention", Mattis said.

On Thursday, the Trump administration accused Assad of producing and using "new kinds of weapons" to deliver deadly chemicals.
