"We regard such statements as another example of megaphone diplomacy and evidence of Washington's irrepressible desire to accuse Russia of all mortal sins. We have repeatedly told the US: if you have any suspicions, then they should be transmitted through official channels with the provision of specific facts and evidence," the envoy said, TASS reported.
"Fake propaganda and a demonstrative refusal to engage in professional dialogue undermine international information security," he stressed.

"The US side is well aware of this," he concluded.
Earlier, the US condemned cyberattacks in several European countries purportedly carried out by Russian hackers.
