Tayyip Erdogan, president of Syria's neighbour Turkey, said on Friday he had spoken by phone with Trump and Putin and told both that increasing tensions in the region was not right.
Iran, which has also backed Syrian leader Bashar al-Assad since the conflict began in 2011, also warned of "regional consequences".
The Saturday report said the ministry warned of regional and trans-regional effects and consequences over the attack, .
Trump was also expected to speak with French President Emmanuel Macron, who said on Thursday France had proof the Syrian government carried out the Douma attack and would decide whether to strike back when all necessary information had been gathered.
"It is those who act to violate the prohibition on chemical weapons who deserve our condemnation", Haley said in conclusion.
USA -led strikes impacting the front lines, and certainly any loss of Russian lives, could strip the Kremlin of the opportunity of restricting its response to one of just issuing angry protests, as it did a year ago when the US launched 59 Tomahawk Cruise missiles on a Syrian airbase after a purported Assad chemical weapons attack on Khan Shaykhun in northern Syria.
"Why would the winning side use (chemical) weapons", he said in a video address at a Hezbollah campaign event for Lebanon's parliamentary elections in May.

US President Donald Trump warned of military strikes in response and European Union member France said it had proof the Syrian government carried it out.
And then added, as he had in a multi-tweet statement earlier in the week: "Hopefully someday we'll get along with Russian Federation ... but maybe not", he said.
Russian Federation has several dozen warplanes at Hemeimeem air base in Syria, along with an array of state-of-the-art air defense missile systems and the Bastion missile systems protecting the coast. It did not say how numerous missiles were intercepted by Syrian forces.
Despite the Kremlin s stern words, few expect Russian Federation to seek confrontation in Syria. At a photo-taking session during a Pentagon meeting with his Dutch counterpart, Mattis was asked by a reporter whether he had seen enough evidence to blame the Syrian government.
Hundreds of Syrians are demonstrating in a landmark square of the Syrian capital, waving victory signs and honking their auto horns in a show of defiance.
President Trump has expressed outrage over the deadly assault in the suburb, Douma, and threatened a military response. The Syrian government has denied the accusations. She also told Russian Federation if it had done its job then Assad wouldn't have these weapons.
