The Russian Defense Ministry said in a statement on Thursday that the situation in the town of Douma, just east of the Syrian capital, is "normalizing".
Damascus has denied responsibility for the incident that has widened a rift between the West and Moscow, which backs Syria's Government.
Earlier, US President Donald Trump wrote on Twitter that Russian Federation should get ready for a missile attack on Syria, claiming the missiles will be "nice and new and smart". France has also said it would join the military action.
Russian Federation does not seek praise, only genuine cooperation in the fight against terrorism, Zakharova said, commenting on US President Donald Trump's recent tweet. "Could be very soon or not so soon at all".
Russian Federation has been involved in the Syrian conflict since 2015 and became Syrian President Bashar al-Assad's main ally in the war against armed opposition groups.
On April 7, several media outlets, citing Syrian militants, accused Damascus of carrying out a chemical weapons attack in the city of Douma, located in Eastern Ghouta.
"Whenever the Syrian Army achieves victory in the field, some Western countries rise their voices and intensify their movements in an attempt to change the track of events", Assad said.

Charlotte Caslick, one of Australia's best at these games, didn't come back on in the second half after a head knock. Earlier in the semifinals, New Zealand beat England 17-12, while Fiji needed extra time to beat South Africa 24-19.
Meanwhile, the Assad regime denies using chemical weapons and called the images from the attack fake.
"Our position is perfectly clear and defined. We really want and we really need it", she said.
Russian people and Russian soldiers are there "not for conquering Syrian people, but to protect Syrian people", Zakharova said. Senator Edward Markey, a member of the Senate Foreign Relations Committee, criticised Trump's warnings that he intends to conduct military strikes in retaliation against Assad's use of chemical weapons.
German Chancellor Angela Merkel (R) and Danish Prime Minister Lars Lokke Rasmussen give a joint press conference in Berlin on April 12, 2018.
Analysts agreed that in striking Syria without U.N. authorization - impossible given Russia's repeated vetoes on the Security Council - the United States, Britain, France were relying instead on a nebulous concept of "legal morality".
In Paris, France's Emmanuel Macron upped the pressure on Moscow by stating he had "proof" that the Assad's regime had used chemical weapons, and vowing a response "at a time of our choosing".
He also noted that France would decide whether to strike Syria when all the necessary information has been gathered.
