The Kremlin said Mr Putin warned against rushing to blame the Syrian government before conducting a "thorough and objective probe".
Russian Federation has been a staunch ally of Syrian President Bashar Assad's government and has helped turn the tide of war in his favor since entering the conflict in September 2015. And the three allies are considering a joint military strike in retaliation.
US ambassador to the United Nations Nikki Haley said earlier on Sunday that Washington was preparing new sanctions against Russian Federation over its support for Syrian President Bashar-al Assad. "Russian Federation can complain all it wants about fake news, but no one is buying its lies and its cover-ups". "Russia was supposed to guarantee Assad would not use chemical weapons, and Russian Federation did the opposite". Russian officials denied any involvement during the most violent days of the fighting between the Ukrainian military and Russian-backed forces in eastern Ukraine in 2014, while journalists and Western intelligence agencies reported tanks pouring across the Russian border into the Ukraine.
The suspected poison attack by the Syrian government forces that allegedly killed over 40 people, according to volunteer first responders and activists, has drawn worldwide outrage and prompted the USA and its allies to consider a military response.
"Russia severely condemns the attack on Syria where Russian military are helping the lawful government in the fight with terrorism", the Kremlin said in a statement, its first reaction to the strikes.
The medics said none of the patients were hurt by chemicals.
Meanwhile, reports suggest that French Mirage and Rafale fighter jets were involved in air strikes on Syria together with four frigate warships.
"It's.highly likely an attempt to create complications for the Organization for the Prohibition of Chemical Weapons (OPCW) mission which was just starting its work in Syria's Douma, or an attempt to completely derail it", Interfax quoted Kosachev as saying. It cited the Russian Ministry of Defense. He asked U.N. Secretary General Antonio Guterres to call an open meeting of the U.N. Security Council for Friday.
A day before a team from the global chemical weapons watchdog was to arrive in Douma, just east of Damascus, Sergey Lavrov said Russian experts have already inspected the site of the alleged attack and found no trace of chemical weapons, adding without elaboration that Moscow has "irrefutable information that it was another fabrication".
"Our military specialists have visited this place. and they did not find any trace of chlorine or any other chemical substance used against civilians", Lavrov said.
