"Russia is convening an extraordinary session of the ceasefire task force today at 17:00 [15:00 GMT]," the source said.
According to the source, the "latest development on the ground in relation to the US strike on the Ash Sha'irat airfield" would be discussed at the meeting.
The office of UN Special Envoy for Syria Staffan de Mistura told Sputnik that the envoy was closely following the situation in Syria and consulting with relevant authorities.
The United States launched 59 Tomahawk cruise missiles at the Syrian military airfield in Ash Sha'irat near Homs late Thursday. US President Donald Trump said the attack was a response to the alleged chemical weapon use in Idlib on Tuesday, which Washington blames on Damascus.
After a 2013 chemical weapon attack in eastern Ghouta, Syria, which killed up to 1,500 people, Syria joined the Convention on the Prohibition of Chemical Weapons. The country's decision to join the convention came as result of a US-Russian agreement on the elimination of chemical weapons in Syria under OPCW control. In January 2016, the OPCW announced the completion of the chemical weapons disarmament in Syria.
On Thursday, Syrian Foreign Minister Walid Muallem said that the Syrian government forces had never used chemical weapons against civilians or terrorists and would never do that.
