He specifically pointed to the fact that the statements were made by military professionals, "such as the official representative of the US Central Command, who alleged that the Russian air strikes are aimed at the moderate Syrian opposition."
"The essence of these statements does not change, no matter what. And they are made without mentioning any concrete facts but with reference to anonymous sources," Konashenkov said.
According to him, Moscow expected "the so-called fake human rights observatories and other propaganda outlets" to spread false information in the Western media, in connection with Russia's ongoing campaign to destroy ISIL's terrorist infrastructure across Syria.
At the same time, he pointed to the fact that "they became more careful in their statements" after the tragic events in Paris, the Russian plane crash over the Sinai and the hostage tragedy in Mali.
Also, Konashenkov warned the Pentagon against speculating on "bad and good" terrorists.
"In real life terrorism, as we know…has no comparative degrees and nationality. Terrorism is an absolute evil to be grappled with in all its manifestations," he concluded.
Earlier that day, the Russian upper house of parliament unanimously supported the request of President Vladimir Putin to deploy units of the Russian Aerospace Forces abroad. Syrian Ambassador to Russia Riad Haddad confirmed that Syrian Army strikes, supported by the Russian Aerospace Forces, were being carried out against armed terrorist organizations, not political opposition factions or civilians.
