The Russian Foreign Ministry Spokesperson Maria Zakharova revealed that Moscow documented examples of involvement by US authorities in Russian internal matters related to the crisis in Ukraine, including through the use of the internet.

The diplomat said that Moscow took note of a material posted on the US Department of State's website on April 21 about the special military operation and that the article encouraged US citizens to join the anti-Russian propaganda campaign by using Western information and communication technology tools.

"In essence ... this is the use of personal means of communication, ordinary Americans to spread lies, propaganda and fakes ... Of course, we strongly condemn the actions of the US authorities aimed at direct interference in the private lives of Russian citizens," Zakharova told reporters.

Furthermore, the diplomat stated that Ukraine, with the backing of the US, has begun planning large-scale cyber provocations against Russia.

"It will not be possible to pass this off as cybercrimes committed from the Russian territory, by citizens of our country, preparations have now begun for a large-scale provocation in the cyber environment by the Kiev regime, the United States, the collective West, NATO structures, EU structures, we are fixing this," Zakharova said.

Moscow can not rule out the possibility that the contentious Myrotvorets website was built with the cooperation of the US State Department.

Myrotvorets publishes personal information on Russian and Ukrainian people, international journalists, and members of international organizations it views to be opponents of Ukraine or working against the country's interests.

Ukraine attacks could lead to a "harsh response"

Moreover, the further calls for Ukraine to strike Russian targets will result in a "harsh response" from Moscow, according to Russian Foreign Ministry Spokesperson Maria Zakharova on Thursday.

"I would like Kiev and Western capitals to take seriously the statements of the Ministry of Defense of our country that further provocation of Ukraine to strike Russian targets will necessarily lead to a harsh response from Russia ... We do not recommend further testing our patience," Zakharova told a briefing.

Concerns over escalation in breakaway Transnistria

We regard these actions as acts of terrorism aimed at destabilizing the situation in the region and expect a thorough and objective investigation of all the circumstances of the incident," Zakharova told a briefing.
