According to her, the United States believes that Russia's "invasion" of Ukraine may be preceded by a "manufactured pretext."

“This may include, but not be limited to, the report you are talking about, allegations of provocations in the Donbass, false reports by state media,” TASS quoted her as saying.

Earlier, the Investigative Committee of Russia opened a criminal case on the discovery of mass graves of civilians in the territory of Donbass.

According to the Investigative Committee, in August-October 2021, five spontaneous mass graves were discovered in Donbass and the remains of at least 295 civilians who died as a result of shelling by the Ukrainian military in 2014 were exhumed.
